Japan's Defense Minister Koizumi Shinjiro has again expressed concern over Chinese military aircraft directing radar at Japanese Air Self-Defense Force fighter jets over international waters off Okinawa's main island in southern Japan on Saturday.
Koizumi told reporters on Tuesday that generally speaking, using radar for searching purposes does not involve intermittent aiming of the device in a way similar to the incident. He said the act is dangerous.
He added that Japan does not believe that it has been given flight and navigation information over sea and airspace related to China's navy training in advance.
In reaction to Japan's announcement of the incident, China criticized Japan, claiming it disrupted a military training drill being held there.
Koizumi referred to a post on Monday on X by US Ambassador to Japan George Glass. He wrote "the US-Japan Alliance is stronger and more united than ever."
Koizumi said the timing of the message shows that the bilateral alliance is always functioning as a deterrent, adding that this is important. He said he hopes to continue having various communications with the US government.
