A delegation of officials and business leaders from China’s Heilongjiang province traveled to Etorofu, the largest island in the Kuril chain, to evaluate potential joint economic projects. The visit was facilitated by the Sakhalin Oblast government, which administers the territory under Russian control. The Kuril Islands have been a subject of a long-standing territorial dispute between Russia and Japan since the end of World War II, with Japan referring to the area as its Northern Territories.

The visit has sparked diplomatic friction, with Tokyo lodging formal protests against the move. While the Chinese delegation aims to foster economic cooperation in Russia’s Far East, the presence of Chinese business interests on the disputed islands complicates the already strained diplomatic landscape between Tokyo and Moscow. Japan maintains that any economic activity on the islands by third parties undermines its sovereignty claims. The SCMP reports that this development is unlikely to ease regional tensions, as it signals a deepening of economic ties between Beijing and Moscow in a region that Japan considers its own sovereign territory.
