The highlight of the latter half of June was the G7 Summit. Japan agreed to strengthen security cooperation with various countries. It has also been conducting joint exercises with the Philippines and the U.S. Marine Corps.

Meanwhile, China and Russia were also highly active. China has been voicing increasingly strong opposition to the start of negotiations between Japan and the Philippines on the delimitation of their exclusive economic zones (EEZs) in the Western Pacific at the end of May. In addition to conducting marine surveys around Taiwan, China has stepped up its provocative actions near Japan. In particular, around June 27, large-scale joint flights by Chinese and Russian aircraft took place, and Chinese and Russian naval vessels were spotted in several waters near Japan.
