Territory
Boundary

China and Russia concluded three years of demarcation work on their 4,300 km Sino-Russian boundary, the longest in the world. In the process, Russia agreed to return to China 174 sq km of territory, consisting of Yinlong Island (Tarabarov Island) and half of Heixiazi Island (Bolshoi Ussuriysky Island), said to be the first place on the mainland to see sunlight. A Chinese official said that China would not station a large military force on the islands.
