Japanese Foreign Minister Fumio Kishida held informal talks with U.S. Secretary of State John Kerry on Monday in Brunei, a Japanese government source said.
During the talks, Kishida and Kerry reaffirmed their plan to hold the so-called "two plus two" meeting of their foreign and defense ministers by the end of the year, the source said.
They also agreed to move ahead with a review of the bilateral defense cooperation guidelines between the U.S. military and Japan's Self-Defense Forces, according to the source.
Kerry also praised that bilateral talks between Japan and South Korea were realized for the first time in roughly nine months, after Tokyo and Seoul pledged to improve ties that have frayed over differing perceptions of history, the source said.
The two met on the fringe of events involving the Association of Southeast Asian Nations and its dialogue partners.
