Since adopting its reform and opening-up policy in the 1970s, China has steadily expanded its relationship with international institutions and transformed its role from passive norm-follower to active norm-maker in the new international order. China’s move to international institutions is characterized by: (1) an economic-led approach to participation; (2) diverse forms of participation; (3) participation on the basis of sovereign equality and peaceful coexistence; and (4) the aim of a fair, transparent international order that considers the interests of developing countries. While China is maintaining its basic position of compliance with existing international rules, its norm-making efforts are demonstrated through its initiatives to establish new international institutional networks. This chapter further examines China’s norm-making role in three major international arenas: peace and security, economic development, and environment and sustainable development. It testifies vividly to China’s increase in soft power as it leads the transition from Western-led global governance to a global co-governance system in which all members of the international community participate.
