Tongjiang (Chinese: ; pinyin: ) is a city of 160,000 in eastern Heilongjiang province, People's Republic of China, located at the confluence and on the right banks of the Songhua and Amur Rivers, the latter which marks the border with Russia. Administratively it is a county-level city of Jiamusi.
From 698 to 936, the kingdom of Balhae occupied northern Korea and parts of Manchuria and Primorsky Krai, consisting of the Nanai, the Udege, and the Evenks and descendants of the Tungus-speaking people and the people of the recently fallen Goguryeo kingdom of Korea. The vicinity of Tongjiang was settled at this moment by Heishui Mohe tribes (Hangul Hanja/Hanzi pinyin : H?ishu? Mòhé). These tribes were submitted to Balhae Kingdom under King Seon's reign (818-830).
King Seon administrated their territories by creating a prefecture in the neighbourhood : The Hoiwon Prefecture (Hangul : Hanja : ) with Dalju (Hangul ? Hanja :) present-day Tongjiang (Hanzi : pinyin :Tóngji?ng), as its administrative centre.
The Tongjiang-Nizhneleninskoye railway bridge was proposed in 2007 by Valery Solomonovich Gurevich, the vice-chairman of the Jewish Autonomous Oblast in Russia. The railway bridge over the Amur River will connect Tongjiang with Nizhneleninskoye, a village in the Jewish Autonomous Oblast.
