Prime Minister Fumio Kishida welcomed U.S. President Joe Biden's call for reforming the United Nations during a brief conversation on Wednesday on the sidelines of a U.N. gathering of world leaders, according to the government.

During a speech before the U.N. General Assembly the same day, Biden expressed his support for expanding the membership of the U.N. Security Council, which Japan has long been hoping to become a part of.

While the details remain unclear, Washington may be viewing Japan, India and Germany as potential candidates to be elevated.
