China has signed the Choice of Court Convention
More (not much more) information is here. Guangjian Tu provided a Chinese perspective on the Convention ten years ago. Two other recent publications are in this context: Zheng Sophia Tang and Alison Lu Xu on Choice of Court Agreements in Electronic Consumer Contracts in China, and King Fung Tsang, Chinese Bilateral Judgment Enforcement Treaties, 40 Loy. L.A. Int’l. & Comp. L. Rev. 1 (2017) (only on heinonline).
