Sovereignty in the South China Sea
In 1949, Communist troops led by Mao Zedong defeated the Nationalist forces led by Jiang Jieshi (Chiang Kai-shek). The Guomindang (KMT) escaped across the Taiwan Strait to the island of Taiwan. The United States continued to recognize the KMT as the government of all China and pledged the US 7th fleet to the so-called defense of Taiwan.
