About
Bolshoi Ussuriysky Island (Russian: Большо́й Уссури́йский о́стров, romanized: Bol'shoy Ussuriyskiy Ostrov), or Heixiazi Island (simplified Chinese: 黑瞎子岛; traditional Chinese: 黑瞎子島; pinyin: Hēixiāzi Dǎo; lit. 'black bear island'), is a sedimentary island at the confluence of the Amur and Ussuri rivers. Since the Sino-Russian Border Agreement that was fully implemented in 2008, Bolshoy Ussuriysky Island was divided between China and Russia. Western part of the island and Yinlong/Tarabarov Island island were returned to China, and Russia retained the eastern part. Since then, the issue has been peacefully settled, and China no longer claims the entire island. It has an area of about 327 to 350 km2 and is bounded closely by Yinlong Island, and over 90 islets. Its position at the confluence of the Amur and the Ussuri, and right next to the major Russian city of Khabarovsk, has given it great strategic importance.
