In February 1943, the International Settlement was "de jure" returned to the Chinese as part of the British–Chinese Treaty for the Relinquishment of Extra-Territorial Rights in China and American–Chinese Treaty for Relinquishment of Extraterritorial Rights in China with the Nationalist Government of the Republic of China under Chiang Kai-shek. However, because Shanghai was under Japanese control, this was unenforceable. In reply, in July 1943, the Japanese retroceded the SMC to the City Government of Shanghai, which was then in the hands of the pro-Japanese Wang Jingwei Government.
