Pianma Incident

Two headmen raised their grievances against Tusi to the Qing Government.

[1] The British accepted their request,[1] tried to induce Tusi to switch allegiance from Qing Dynasty to British Crown and deployed troops to occupy the region.

[2] Britain subsequently forced emerging Republican China (ROC) to give up another portion of territory, Jiangxinpo, in what is now Northern Kachin state of Burma in 1926–27,[2] as well as some part of the Wa states in 1940.

[2] People's Republic of China (PRC) and Burma signed a border treaty in 1960, with the PRC recognizing most of these disputed territories as belonging to Burma,[3] with the exception of Burma relinquishing a small amount of that territory,[4] namely Hpimaw (Pianma) and adjacent Gawlam[3] (Gulang)[5] and Kangfang[3] to the PRC.

The Republic of China (now Taiwan) did not recognize the British seizure of these territories nor the said PRC-Burma agreement ever since.
