evidence: On 28 January 1960, Burmese premier Ne Win visited China and signed a deal aimed at solving the historical territorial disputes between China and Burma (specifically Jiangxinpo and Namwan). In October 1960, Burmese prime minister U Nu and Burmese chief-of-general-staff Ne Win visited China once again; on 1 October 1960, they signed a new border treaty with Chinese premier Zhou Enlai. Before the border treaty was signed, both sides agreed in May 1960 to jointly eradicate the Chinese nationalist force in the border region. The treaty's requirement to survey of the China–Burma border for demarcation provided reasons for the following military actions.[2] [...] The nationalist 4th Army deployed to the south and east of Mengyong (孟勇) was the backbone of the nationalist 2nd line of defence, and its 35th Regiment (totalling over 200 soldiers) was stationed at the critical peak 1404. The Mengbailiao (孟白了) and Jiangle (江拉) regions were the nationalist 3rd line of defence; the general headquarters of the nationalist commander-in-chief Liu Yuanlin (柳元麟) were setup in Mengbailiao (孟白了), with the training group, garrison regiment and communication battalion totalling over 450 troops. The Jiangle (江拉) region was the nationalist logistic headquarters. It totalled over 200 troops, including the 1st Training Group.
