Prime Minister Fumio Kishida and his Cambodian counterpart, Hun Sen, urged Russia on Sunday to immediately end the war in Ukraine and withdraw its forces from the country, condemning the aggression as "a grave breach of the United Nations Charter."

In a joint statement issued after their meeting in Phnom Penh, the leaders also called for the immediate cessation of violence in coup-hit Myanmar and demanded that the junta release ousted civilian leader Aung San Suu Kyi and other detainees and restore the democratic political system.

Kishida and Hun Sen "recognized that this aggression jeopardizes the foundation of international order which does not accept any unilateral change of the internationally recognized borders by force," according to the statement, although it did not single out Russia.
