This rejoinder to Daniel Twining’s article in the last issue (48:2, June 2013) of The International Spectator argues that both China and the United States recognise how important their relationship is for the world and the Asia-Pacific in particular. But the risk of tension on the security front has increased recently due to the US’ policy toward maritime disputes that has actually involved meddling between the parties involved, and its ‘pivot’ to Asia which targets China with more military engagement in the region. The China–US relationship has never been an easy one with the US certain of its primacy and China proud of its glorious past, which almost makes a conflictual power transition a self-fulfilling prophecy. Management of the relationship is the key for both countries to bring about more cooperation and to rein in competition. Co-evolution, a new type of relationship among major countries, is the only way out, in which the logic of interaction is ‘live-and-let-live’ rather than mors tua, vita mea.
