The United States reiterates its support for Japan’s sovereignty over islands that Russian President Vladimir Putin visits during a trip to four islands in the disputed Kuril chain. After the visit, the U.S. ambassador to Japan says Washington is “unwavering” in its position that the islands belong to Japan.

In response, Japan summons Russia’s ambassador and considers options including tightening sanctions against Russia. Moscow says the islands are Russian territory and that they are not subject to discussion with foreign governments. Different outlets frame the same diplomatic exchange around Washington’s reaffirmation and Tokyo’s reaction, while reporting Moscow’s opposing claim.

Overall, the episode follows long-running disputes rooted in post-World War II control of the islands, with the latest statements centering on competing sovereignty claims and the possibility of further diplomatic and economic pressure.
