The island was occupied by the Soviet Union in 1929, a move not accepted by China, resulting in a border dispute that lasted more than seventy years.

On October 14, 2004, the Complementary Agreement between the People's Republic of China and the Russian Federation on the Eastern Section of the China–Russia Boundary was signed, in which Russia agreed to relinquish control over a part of Abagaitu Islet. In 2005, the Russian Duma and the Chinese National People's Congress approved the agreement.
