evidence: Discussions between Burma and China over the border began in 1954, with China keen to control the area more effectively as it was being used as a base by Kuomintang troops.[2] On 28 January 1960, a treaty was signed which delimited most of the border, which was later completed with a full delimitation treaty signed on 1 October 1960, with both sides ceding small areas along the border, such as areas around Kachin Hills/Jiangxinpo[2] and Wa States,[6] which China recognized most of the disputed territory belonging to Burma, while Burma relinquishing small amount of that disputed territory,[7] namely Hpimaw (Pianma) (片馬; 片马; Piànmǎ)[8] and adjacent Gawlam (Gulang) (古浪; Gǔlàng)[9] and Kangfang[2] (崗房; 岗房; Gǎngfáng)[10] to PRC. They also agreed that Namwan area (which was in "perpetual lease" from China to Burma) would become part of Burma legally, in exchange for Burma ceding Panghung/Banhong and Panglao/Banlao to China.[2] The two sides then demarcated the border on the ground in the following year.[2] The border ran through the Wa region, although it had little practical effect on the Wa people.[11]: 13
