This chapter offers a plausibility probe of IST in the case of China and the contemporary liberal international order. The LIO – a multifaceted set of institutions covering a range of security and non-security issues – has contributed immensely to China’s economic growth, diplomatic influence, and national security. China, nonetheless, opposes some and embraces other parts of the international order. The chapter shows that existing theories of revisionism struggle to explain this pattern of cooperation and discord in China’s approach. It then traces China’s status aspirations in the post-Cold War period and applies IST’s predictions to China’s stances in various prominent international institutions. The chapter concludes that IST can broadly apply in this case across institutions and issue areas, though further research is required to decisively demonstrate this claim.
