evidence: Jiangxinpo was an area currently in Kachin State, Myanmar, located between the N'Mai and Mali Rivers, west of the Gaoligong Mountains of Yunnan, China. It was previously under the rule of the Qing dynasty of China. [...] It was disputed territory between China and Myanmar until 1961, when People's Republic of China (PRC) recognized Myanmar's sovereignty over it,[4] with the exception of Burma relinquishing small amount of that territory,[5] namely Hpimaw (Pianma) and adjacent Gawlam (Gulang) [6] and Kangfang[4] [7] to PRC, as part of Lushui county. Some Chinese commentators, especially those media in ROC (Taiwan)[4] and overseas which are outside the control of PRC government's censorship, criticized the PRC government for signing the agreement, which they regarded as guaranteeing the permanent loss of former Chinese territory to Myanmar.
