1960–1961 campaign at the China–Burma border

The campaign at the China–Burma border (simplified Chinese: 中缅边境作战; traditional Chinese: 中緬邊境作戰) was a series of battles fought along the China–Burma border after the Chinese Civil War, with the Communist People's Republic of China (PRC) and the Union of Burma on one side and the Nationalist forces of the Republic of China (ROC) on the other. The Chinese government refers to the campaign as the China–Burma border demarcation and security operation (中缅边境勘界警卫作战; 中緬邊境勘界警衛作戰).
