The 1909 Gando Convention (: Jiāndǎo XiéyuēKorean: ) was a treaty signed between Imperial Japan and Qing China in which Japan recognized China's claims to Jiandao, called Gando in Korean, and Paektu Mountain. Japan received railroad concessions in Northeast China (Manchuria). After the Surrender of Japan, Gando Convention was de jure nullified and North Korea started to control the area south of Paektu Mountain.
