The continuous but rocky developments of Sino-South Korean relations: examined by the four factor model

ABSTRACT Since the establishment of “friendly and cooperative relations’ in 1992, relations between South Korea and China have been continuously elevated almost every 5 years. The two countries have achieved great advancements in expanding civil exchanges, bringing economic relations closer, finding common ground in foreign policy and security and elevation of political relations. Despite the honeymoon period that the two countries experienced after they established diplomatic relations, however, conflict is now arising due to differences in opinion and interests in various fields such politics, economy, society, culture, diplomacy, and security. This paper will examine Sino-South Korean relations using the four factor model, which is based on four approaches, starting with economic relations, followed by perception and emotions, diplomacy and security and lastly, these factors” influence on domestic politics. Following this analysis, this paper will argue that despite their continuous but rocky developments, Sino-South Korean relations will sustainably maintain their development. Considering the synergy effect of bilateral relations, two countries are standing on the opportunity to build a New Type of Sino-South Korean relations which would allow for resolution of conflicts and misunderstandings through dialogue and communication.


Introduction
August 24 th , 2020 marked the 28 th anniversary of the establishment of Sino-South Korean diplomatic relations 1 On that day in Beijing in 1992, the two sides established friendly and amicable relations based on reciprocal equality and peaceful coexistence and signed a joint statement mutually confirming the "One China" principle as well as a "peaceful reunification of the Korean Peninsula," ushering in a new era. The establishment of Sino-South Korean relations is remarkable from historical and civilizational perspectives, in that Seoul and Beijing settled long-standing antagonisms, reconciled and resolved ideological and inter-systemic confrontation, and heralded the end of the Cold War in Northeast Asia. China and Korea have seen great advancement in almost all areas, encompassing politics, economy, society, culture, diplomacy and security. factors that influence Asian neighbors' bilateral relations with China, with South Korea as case study. Based on the initial research plan, it is based on four approaches, starting with economic relations, followed by perception and emotions, diplomacy and security and lastly, these factors' influence on domestic politics

Economic relations
The area with most notable success between the two countries is economy and trade. During the 10 years following the establishment of diplomatic relations in 1992, both countries enjoyed a win-win division of labor, in which Korea was a relatively advanced economy and China a late-comer developing state. Korean technology and investments, combined with China's cheap manpower and raw materials created mutual benefits. Taking advantage of the two countries' geographic proximity, Korea was able to create an international division of labor system that combined Chinese labor with Korean exports of intermediate goods and investments by its companies. The economic crisis in the beginning of the 21 st century accelerated the trend toward economic integration in East Asia, and the mutual recognition for the necessity of an FTA shared by both sides resulted in the finalization of the negotiations in November 2014.
Trade volume between the two sides has grown almost 39 times from US$6.3 billion in 1992 to US$243 billion in 2019. With exports to China reaching US$136.2 billion and imports from the country totaling US$107.2 billion, Korea's trade surplus with China amounts to US$29 billion. In late 2019, China was Korea's biggest trading partner. Likewise, Korea was the largest exporter for China, the 3 rd largest importer of Chinese goods, as well as its 3 rd largest trading partner, excluding Hong Kong. The cumulative amount of Korea's investment in China up to 2019 is at US$70.8 billion 4 This accounts for 13.7% of South Korea's foreign investment globally, and since 2008, China has been the second largest recipient of Korean investment after the United States. The FTA between the two countries has become the backbone of their economic relations, and a currency swap agreement has also been concluded 5 But recently, the nature of Sino-South Korean relations is beginning to change, which is largely attributable to the development of the Chinese economy. The impact of Chinese economic competitiveness is already being felt globally. There are even some analysts who say that a new Cold War between the U.S. and China is upon us, with the West, including the United States, holding China responsible for the COVID-19 pandemic in addition to the de-Sinicization of supply chains and China's isolation from technology and finance. For developing countries to become developed countries, it is necessary to secure technology, and as China has successfully made great strides in 5 G, a key technology of the fourth industrial revolution, the U.S. has started to implement a strategic decoupling with China. It is expected that China will surpass the U.S. and become the world's largest economy by the year 2030, at the earliest 6 China's industrial upgrading is not only affecting the division of labor structure between South Korea and China, but is also causing Korea much worry in terms of its competitiveness within the Chinese market and if it will be able to maintain its trade surplus with China and its technological superiority 7 In particular, the greatly reducing technological gap between Korea and China has been giving rise to concerns throughout the Korean economy. The industrial and export structures of both countries share considerable similarities, making competition in the global market inevitable. The technological gap between Korea and China is said to have been narrowed to only a couple of years. Except for semiconductors, displays and wireless communications, only a few areas remain in which Korea maintains technological advantage over China. Even Korean semiconductors already seem to have lost some of their competitiveness against Chinese products 8 China's economic sanctions on Korea following the latter's deployment of THAAD have particularly shrunk Korean corporate activities within China 9 In addition, various economic policies have been proposed under Xi Jinping, such as the Chinese Dream, Xin Chang Tai (new normal), supply-side structural reform, and Made in China 2025. Due to U.S.-China trade friction and the COVID-19 pandemic, external conditions have also worsened, leaving China's export-driven economic growth model to reach its limit.
Dual Circulation, which became a new buzzword in 2020 after President Xi Jinping had mentioned it several times, refers to a strategy of pursuing economic growth through the expansion of the domestic economy and international trade, while also creating synergy between the dual axes of domestic circulation and international circulation. China's Dual Circulation policy may be an opportunity for Korea's economy, but it may also be a threat. In the process of promoting its Dual Circulation policy, the Chinese government is likely to strengthen its state-led economic system. China's strengthening of its state-led economic system does not bode well for East Asian economic integration, including integration with the Korean economy. The strategic competition between the U.S. and China in the Trump era was bilateral in nature 10 And like under Trump, U.S.-China relations under Biden are also predicted to be more competition-focused than cooperation-focused, meaning the future of economic relations between Korea and China are not looking optimistic.

"'The Chinese economy will overtake the US's in 12 years' a think tank in China said," Donga Ilbo, September 3 2020. 7 Yang, "Trade and Investment," 107, 121. 8 "Technological gap between Korea and China narrowing rapidly . . . Even semiconductors not safe from competition in a couple years," Chosun Ilbo, December 9 2017. 9 A good example of Chinese economic retaliation due to THAAD is the case of Lotte Mart in China. The Chinese retaliation targeting Lotte began in September 2016 after the announcement by the South Korean government that Lotte's golf course in Seongju, North Gyeongsang Province was chosen as the site for THAAD. There were already talks about Lotte Mart's withdrawal from the Chinese market amid strong competition from domestic suppliers, but after the deployment of THAAD at the Seongju golf course, political pressure also began to be applied. Additionally, it is widely accepted within South Korea that Chinese retaliation for THAAD also occurred less overtly in the culture, tourism, and "Hallyu" (Korean Wave) sectors.

Perception and emotions
Throughout their long histories, Korea and China have continuously interacted, but following the Korean War in 1950, exchange was cut off, and both sides lost interest in each other. Only after diplomatic relations were established in 1992 were humanitarian, social, and cultural exchanges reinstated 11 Social and cultural exchange is also a growing area. As of 2018, people-to-people exchanges between Korea and China have increased by 69-fold from 130,000 in 1992 to 8.99 million in 2018. In addition, 70,000 Chinese students take up the largest share among international students studying in Korea. The number of airline flights amounts to 1,240 per week 12 So the craze over the Korean wave and the Chinese Wind remain intact. But with the rapid development of relations, negative aspects have also followed 13 A series of events that took place since the establishment of diplomatic relations have spurred the outburst of anti-Chinese sentiments in Korea 14 Such sentiments refer to tendencies to dislike and hate China. It goes beyond the hostility solely against the Chinese government due to contentions in issues of politics and history, but it has spread to hatred toward China itself and its people. One of the first events that triggered such sentiments was the 'garlic crisis' 15 After the Korean government imposed tariffs on Chinese garlic, Beijing responded by imposing a great sum of tariffs on Korean-made cellphones. Subsequently, China's Northeast Project, starting in 2004, attempted to distort Korea's ancient history 16 , and in 2005, Beijing protested after Korea registered the Gangneung Dano Festival as a UNESCO World Intangible Heritage 17 In addition, the fine dust issue, illegal fishing by Chinese boats and China's imitation of Korean products and the Korean wave are also factors that aggravate the hateful sentiments toward China. Since 2020, the mutual attacks by netizens of both countries regarding the origin of hanbok and Korean food have been intensifying.
After the establishment of diplomatic relations, the mutual perception of the two countries has went through three stages. 1992 to 2003 was a honeymoon period, then up until 2008 was a period of deepening cultural conflict, and then following the 2008 financial crisis, political and diplomatic conflicts caused by China's aggressive, Sinocentric rise led to a negative shift in public perception. During the 2013-2016 Park Geunhye administration, there was a brief period of improved South Korea-China relations thanks to President Park's 2015 visit to Beijing for China's Victory Day celebrations. But then following the controversy surrounding the deployment of THAAD in South Korea in 2016, anti-Chinese sentiment among Koreans was raised to extreme heights 18 Korea's cultural and psychological perceptions and emotions toward China are complex 19 The psychological basis of Koreans' disdain for China is the dual feeling of fear of China's rise along with Korea's sense of superiority regarding its economy and political system. This sort of sentiment is in line with Korea's unwillingness to acknowledge the changes that China is going through, and it also shows that Korea's perception of China is still stuck in the 1980's 20 For thousands of years of history, with the exception of the kingdom of Goguryeo, which saw the greatest territorial expansion by a Korean state in history and was able to hold its own in confrontation with the powerful Chinese Sui and Tang dynasties, Korea has had to yield to China. It is because of this history that Korea has an inferiority complex toward China and why Korea tends to implicitly flaunt its superiority.
Bilateral relations have been largely negative since the establishment of the Republic of Korea due to differences in ideology and political culture, as China was seen as the main contributor to the fratricidal conflict that was the Korean War in 1950. China being a socialist state and events like the Cultural Revolution also affected the perception. China was also economically backwards, so up until the early 2000s, there was a belief that Korea was superior in terms of economy and culture. There is still a strong perception of China being an "emerging nation" or a "human rights abuser" yet to become a developed country, but as an emerging power, "national power of China, a G2 nation on par with the U.S." are also accompanying labels. Accordingly, Koreans are not very much fond of China. They perceive China as more of a threat, although it is at the same time a necessary partner to cooperate with for the reunification of the Korean Peninsula, alleviation of North Korean threats 21 , and for economic gain. But Beijing's passive stance in the issues of reunification and denuclearization along with increased economic competition between the two nations have led Koreans to be more wary. 18 This was shown in the rapidly declining favorability toward China among Koreans. After the decision by the USFK to deploy THAAD, Chinese economic retaliation accelerated, and favorability toward China among Koreans dropped lower than that toward Japan, despite the "comfort women" and Dokdo issues. According to the results of a monthly poll published by the Asan Institute for Policy Studies in March 2017, the favorability toward China among Koreans in March was 3.21 out of 10. The closer to 10, the higher the favorability toward the country. This is 0.12 points lower than Japan's favorability rating among Koreans (3.33 points) in the same month.

Security and international environment
The establishment of diplomatic relations between Korea and China took place in the context of changing international affairs, namely the collapse of the Cold War system. In the late 1980s the Roh Tae-woo government (1988)(1989)(1990)(1991)(1992) introduced a progressive foreign policy vis-à-vis the Eastern Bloc countries such as China and the former Soviet Union. This so-called "Nordpolitik" eventually led to the opening of diplomatic relations with China. And it was the Kim Young-sam government (1993)(1994)(1995)(1996)(1997) that laid the foundation for Sino-South Korean relations, and subsequent governments under Kim Dae-jung (1998Dae-jung ( -2002 and Roh Moo-hyun (2003Moo-hyun ( -2007) that expanded cooperation with China while prioritizing strategic values. During the presidencies of Lee Myung-bak (2008Myung-bak ( -2012 and Park Geun-hye (2013-2016), relations deteriorated and accumulated tensions erupted. The current Moon Jae-in government (2017-) is attempting to seal the THAAD issue and to create a new breakthrough in relations 22 Sino-South Korean relations have been continuously elevated phase by phase. It started out as a "Friendship and Cooperative Relationship" in 1992, which then was elevated to "ROK-China Collaborative Partnership for the 21 st Century" in 1998, followed by a "Comprehensive Cooperative Partnership" in 2003, and a "Strategic Cooperative Partnership" in May 2008. In June 2013, the "Strategic Cooperative Partnership" was fortified with more substance, which, in 2017, came into effect 23 This can be seen as the highest point of the bilateral relations, which had been elevated almost quinquennially.
Notable is also the fact that, for the first time, a Chinese leader made a visit to South Korea before going to the North. President Park attending the Victory Day parade in 2015 marked a high point in Sino-South Korean relations, but the subsequent THAAD deployment brought it down to its lowest, leading Beijing to turn to the strategic value of North Korea once again. Nevertheless, under President Moon bilateral relations are changing for the better, despite the bumpy start. In particular, when the COVID-19 outbreak first began in Wuhan, China, the Korean government did not ban Chinese citizens from entering South Korea and made friendly political gestures, such as sending masks. Thanks to this, both governments were able to significantly reduce the after effects of the THAAD controversy. COVID-19 is also considered a new area of cooperation between South Korea and China 24 In actuality, South Korea is a fair and reasonable partner for China when it comes to mutual economic benefit, mutual security gains and international order, but the Korea-U.S. alliance and North Korea's denuclearization remain as conflict factors. North Korea is not the only constant variable in Sino-South Korean relations 25 The U.S., an ally of South Korea, is also a variable with much more weight than North Korea. America's commitment as an ally, the protection it provides, and the price of that protection are factors that influence Sino-South Korean relations. The deployment of middle-range missiles or Korea's participation in the U.S.'s Indo-Pacific Strategy, along with the issue of additional deployments of THAAD, could emerge as other sources of conflict between Seoul and Beijing in the future within the context of intensifying U.S.-China confrontation. Therefore, China hopes for a Korea more independent from the U.S., capable of voicing its own stance more assertively. One must pay attention to the strategic implications on Korea's security arising from the dynamics of the U.S.-China relations 26 The dichotomous logic of "relying on the US for security and on China for the economy" puts South Korea in a strategic dilemma. Whenever an issue arises, Korea is often forced to choose between the U.S. or China 27 When the U.S.-China relationship is stable, it can facilitate inter-Korean dialogue and reduce tensions; but it can never guarantee Korea's national interest 28 China will attempt to secure its own influence in the issues of denuclearization and a peace agreement, for which it will set out a strategic roadmap. It is important that Korea's position be sufficiently reflected in it. One should also realize that the expectation toward North Korea for sincerity could be different in China. China will take into account not only Sino-South Korean relations, Sino-North Korean relations and inter-Korean relations, but also the bigger context of U.S.-China relations.

Correlation with domestic politics
The domestic politics of Korea exhibit a number of characteristics 29 The most prominent one is that the personality of a leader counts more than the political party. To put it simply, the Peace Democratic Party in 1987, the Democratic Party in 1992, and the National Congress for New Politics in 1996 were all essentially Kim Dae-jung's party. His followers remained around the central figure Kim Dae-jung 30 A party is like an outfit that can be changed at will, and the names of the parties are also easily altered. Other politicians, including the incumbent President Moon, are no exceptions to this. But the overall power landscape remains unchanged, which can be divided into conservative and liberal. It is not easy for moderate politicians to gain a footing between these two forces. Politics is very fierce and is one of the most dynamic in the world, to put it mildly. It is almost antagonistic, to put it more bluntly 31 26 Medeiros, "The Changing Fundamentals of U.S.-China Relations," 93-119. 27 As mentioned above, THAAD is a good example. Recently, the United States has been asking for South Korea's participation in US pressure on Huawei. Even if South Korea participates in the US-led anti-Huawei pressure campaign, South Korea's relationship with China, with which it maintains close economic cooperation, will suffer. Therefore, South Korea is trapped in a dilemma in which it cannot strengthen relations with Huawei or China as it pleases. Choi, "[IT Curation] Huawei all alone; South Korea must walk the tightrope to the very end," Economic Review, October 312,020. 28 For a perspective on the utility of the Korean peninsula as a cooperative aspect instead of the usual competitive aspects in U.S.-China relations, see: Sutter, "Relations with Japan and  For a study on the correlation between domestic politics and foreign policy, see: Kang, "How does domestic politics influence foreign policy?: System and leaders,"; Chiozza and Goemans. "International Conflict and the Tenure of Leaders: Is War Still Ex Post Inefficient?" 604-19. 30 Kim Dae-jung was the 8th president of South Korea (1998Korea ( -2003. For his contributions to the improvement of human rights and progress in inter-Korean relations, he was the first Korean ever to receive the Nobel Peace Prize during his term in office in 2000. 31 For a study on the correlation between the decision-making process of a foreign policy and democracy, see: Kim, "Korean Foreign Policy and Problems in the Democratization Era," 271-92.
According to one research, the ideological tendencies from progressive to conservative have a significant impact on perceptions toward China. The role of ideology in the sense of the perception toward China has been strengthened. In this context, the impact of liberal ideology on recognition of China is weaker than conservatives, on the other hand, their preference for China is relatively higher than the conservatives. Furthermore, this perception toward China is formed with overlapping traditional crack of "anticommunist vs pro-North Korea" and "pro-ROK-U.S. alliance vs self-reliance." This crack eventually influences the domestic division 32 The importance of Korea's China policies has continuously increased since the opening of diplomatic relations in 1992. There have been four conservative governments including those of Roh Tae-woo, Kim Young-sam, Lee Myung-bak, and Park Geun-hye; and three progressive governments under Kim Dae-jung, Roh Moo-hyun, and Moon Jaein. It was Roh Tae-woo who established diplomatic relations with China, which he considered to be the pinnacle of his Nordpolitik. Establishing relations with China followed by Russia after the breakup of the Soviet Union allowed South Korea to gain the diplomatic upper hand over North Korea. Under President Lee Myung-bak, priority was given to the Korea-U.S. alliance while focusing solely on economic benefit with China. Park Geun-hye, even as a conservative, achieved the best relationship with China since 1992, attending China's Victory Day Parade and signing the FTA, but on her watch, relations also plummeted to their worst with the THAAD deployment and the disappointment at the lack of Chinese support on the denuclearization issue.
Sino-South Korean relations generally remained stable under liberal governments. China thought highly of Korea during the Kim Dae-jung presidency as he was able to make strategic decisions in the midst of America-centered diplomacy, keeping reunification in mind. Moreover, his Sunshine Policy helped enhance rapport with China. President Roh Moohyun had to go through the Goguryeo historical disputes, but he constantly sought a close partnership with China. Although Moon Jae-in inherited from the previous administration frosty South Korea-China relations due to the THAAD issue, relations were able to normalize thanks to consensus on North Korea policy and through cooperation on COVID-19.
Against this backdrop, three observations can be made. Firstly, friendly attitudes toward China become more likely depending on the individual personality of the South Korean leader. The clearest example is that of President Park Geun-hye. She was able to directly and indirectly show goodwill to China by expressing her sympathy for President Xi Jinping's family background and the changes that occurred throughout his life, and by doing so was able to bring Sino-South Korean relations to their highest point ever. Second, Sino-South Korean relations do not wholly depend on the political orientation of the Korean leader and his or her political party affiliation. It was during Roh Moo-Hyun's presidency that the ROK-U.S. alliance was strengthened, for example, by sending Korean troops to Iraq. And it was President Park that concluded the FTA with China and attended Beijing's Victory Day Parade in 2015. Third, positioning between the U.S. and China remains an inevitable dilemma for all South Korean governments. Korea's foreign policy will likely spur much heated debates in domestic politics in the future 33 Since the establishment of "friendly and cooperative relations" in 1992, relations between Seoul and Beijing have been continuously elevated almost every 5 years. There is a considerable overlap of interest which goes beyond cultural affinity, geographical proximity and economic interdependence, including peace and stability on the Korean Peninsula. Accordingly, the development of bilateral relations is a historical trend, which is why one should not be preoccupied with each particular situation nor overreact at each conjuncture. Considering the synergy effect of bilateral relations, two countries are standing on the opportunity to build a New Type of Sino-South Korean relations which would allow for resolution of conflicts and misunderstandings through dialogue and communication.
A New Type of Sino-South Korean Relations can be defined as follows. There had been too much expectation placed on each other in the course of the rapid development. Both sides anticipated support and understanding from the other, and this state of vague expectation led to misunderstanding and disappointment. The differences in the interpretation of the strategic cooperation agreement is such an example. In Chinese terms strategy refers to something of a middle and long-term, whereas for Koreans it means security and military support.
The current administration has already proclaimed a substantive strategic cooperative partnership with China, but in order for reality to match this proclamation, a few types of strategic cooperation must be possible. First, both countries should cooperate to create a safer security environment. In other words, they can work together for peace and stability in Northeast Asia and especially for the future of the Korean Peninsula. Second, both countries should cooperate to create a more developed economic environment. That is, joint economic development may be achieved on the basis of rational and comprehensive agreement on sustainable economic cooperation. Third, they should cooperate to create an improved human security environment, i.e., they may cooperate on transnational and nonmilitary security issues such as disease, disaster, crime, environment, and terrorism. Continuing, there should be 3 mechanisms in need. First, the crisis prevention and management mechanism in the Blue House level, second, 2 + 2 diplomatic and economic high-level strategic dialogue mechanism at government level, and third, military trust mechanism through non-traditional security cooperation in military level.
However, as the four factor model examination has shown, China, once an economic opportunity for Korea, has now become a threat to the Korean economy, and competition between the two sides is intensifying in the global market. The Moon Jae-in government has been improving political and diplomatic relations with China, but when we look at the case of THAAD, it is evident that strong economic ties do not necessarily guarantee a stable relationship. And during the remainder of the Moon Jae-in administration and going into the post-Moon era, tense Sino-South Korean relations will persist in every field, including politics, economy, society, and culture. Nevertheless, the governments of both South Korea and China must adopt and develop the ideas discussed above for the future development of their bilateral relationship. Once this kind of cooperation becomes possible and its mechanism is set into motion, the two countries will be able to make their strategic cooperative partnership "substantive" in the truest sense of the word. Strategic cooperative partner should not remain an empty slogan, but be translated into action.
