图们江
The farmers, unwilling to abandon their homes, argued that because of the ambiguity in the naming of the Tumen river, they were actually already in Korean territory. The Yalu River boundary is of little dispute, but the interpretation of the Tumen River boundary 土門 (토문) causes problems. The name of the river itself originates from the Jurchen word "tumen", meaning "ten thousand". The official boundary agreement in 1712 identified the Tumen river using the characters 土門 (pinyin: Tǔmen) for the phonetic transcription. However, the modern Tumen River is written as 圖們 (pinyin: Túmen) in modern Chinese and as 豆滿 (두만) "Duman" in both modern Korean and Japanese. Some Koreans hence claim that the "Tumen" referred to in the treaty is actually a tributary of the Songhua River. Under this interpretation, Gando (where the Koreans settled) would be part of Korean territory.
