Abstract: China has in recent years been actively engaged in multilateral diplomacy. From the Shanghai Cooperation Organisation and the Conference on Interaction and Confidence Building Measures in Asia to the Asian Infrastructure Investment Bank and the One Belt, One Road initiative, Beijing is pursuing strategies and promoting norms that are viewed as concerted efforts by China to challenge some of the key institutional arrangements of the existing international order. This article seeks to discuss these contentious issues and assess the rationales, approaches and implications of Chinese diplomacy in initiating and promoting what can be considered as institutional-balancing strategies. The author suggests that the rationales behind these Chinese strategies have as much to do with Beijing’s shifting priorities and the need to address them as with reflecting a degree of dissatisfaction with existing multilateral institutions. And there are more marked differences in Chinese motivations and modalities in security arenas than in economic areas. However, it would be overstating Beijing’s intentions and capabilities if these China-sponsored initiatives are viewed as direct challenges to the existing international and regional orders.
