In an imbalanced international environment, China needs to improve its institutional discursive power by taking more initiatives in global affairs. Institutional discursive power was firstly put forward in Communique of the Fifth Plenary Session of the 18th Central Committee of the CPC. The present study redefines it to fit the needs of the global standing China is finding itself in, with an emphasis on innovating institutional discursive power. It is found that China has been using four approaches to improve its institutional discursive power. Participating in international organizations and systems is necessary in China’s early stage of development, but there are too many constraints for China. Post-participation reform is feasible, but it precludes long-term mechanisms. Building new international organizations and promoting them together with other countries is beneficial for tackling global challenges. However, the Boao Forum for Asia and the BRICS both have limited co-operations. The single-handed founding of new global organizations is an important step for China to exercise its global influence and exercise its leadership. The Belt and Road Initiative and AIIB represent China’s ability and determination in creating and offering global public goods, thus to improve global governance on its own. It is suggested that this be a key approach to China’s enhancement of its soft power on the globe.
