along with an explanation that its issuance was an "administrative error." A small number of South Korean activists believe that under a unified Korea, the treaties signed by North Korea can be deemed null, allowing the unified Korea to actively seek regress for Gando. However, the current political situation makes this a faint possibility at best. Also, some scholars claim that China's efforts to incorporate the history of Goguryeo and Balhae into Chinese history is an effectively pre-emptive move to squash any territorial disputes that might arise regarding Gando before a unified Korea can claim such or the Korean ethnic minority in the Manchuria region claim to become part of Korea. Images The following maps, made by Korea from the 18th century to the 19th century, show Sino-Korean borders to be aligned along the Yalu and Tumen Rivers, essentially the same as those today (between China and North Korea): However there is an exception in the last map, as it shows the border visibly protruding north of the Tumen River. Some Korean claims to Gando are based on other maps. The following were made by western missionaries. However, the first is explicitly stated as a map of "Quan-Tong Province" (now Liaoning province, China) and Kau-li (Korea), and the second is stated as a map of the Chinese Tartary (la Tartarie Chinoise). Compared to the Korean-made maps above, the coastlines and rivers are also significantly less accurate, but the Sino-Korean border is not placed at the Yalu/Amnok River, which is quite clear in the following maps: Note that two almost identical versions of a first map exists, showing significant differences in the border. One shows the boundaries similar to modern-day province and country borders, while the other shows the Sino-Korean border significantly further north.
