Jiangxinpo is a territory of Republic of China
Jiangxinpo is located between the Xien Meikai River and Mailikai River in the Gaoligong Mountains of Yunnan, China, with an area of ​​about 27,000 square kilometers, a length of about 300 kilometers, and a width of about 150 kilometers.

According to the "Boundary Treaty between the People's Republic of China and the Union of Myanmar Government" signed by Zhou Enlai and U Nu in 1960, The People's Republic of China gave up its territorial claim to Jiangxinpo and took back from Burma the Pianma, Gulang and Gangfang occupied by the British in 1913. On June 18, 1941, the Chinese and British governments exchanged notes, and the Banhong and Panlao tribal areas in Myanmar were assigned to China and became part of Chinese territory.
