Two Chinese bombers and two suspected Russian airplanes on Wednesday flew above the Sea of Japan, the Japanese Defense Ministry said, with its Air Self-Defense Force scrambling fighter jets in response.
The two Chinese H-6 bombers flew through the Tsushima Strait in southwestern Japan from the East China Sea to the Sea of Japan in the morning before heading northward while the two suspected Russian aircraft reversed their direction from southward and headed for the north above nearby waters, the ministry said.
The ministry is collecting information on further details, while trying to find out intention of the flights.
On May 24, China and Russia flew six strategic bombers over waters near Japan, according to the ministry, in what then Japanese defense minister believed was a protest against a Quad summit held the same day in Tokyo, involving Japan, the United States, Australia and India.
