evidence: China has published a map that appears to revise its territorial borders to lay claim to large swathes of territory owned by its neighbors, including the island of Bolshoy Ussuriysky, part of which is in Russia. [...] Bolshoy Ussuriysky and the neighboring island of Tarabarov were taken "under protective custody" by Soviet troops in 1929. Both islands remained under Russian control after the collapse of the Soviet Union in December 1991. Tarabarov, part of Bolshoy Ussuriysky and some smaller islands—Vinogradov, Koreysky, Romashkin—were handed over to China on October 14, 2008, with experts noting at the time that the move benefited the stability of bilateral relations.
