LONDON - Foreign Minister Toshimitsu Motegi and his British counterpart Dominic Raab on Monday affirmed security cooperation in promoting a “Free and Open Indo-Pacific" as China steps up assertive territorial claims in the East and South China seas. Meeting on the sidelines of a three-day gathering of Group of Seven foreign ministers in London through Wednesday, Motegi welcomed Britain's scheduled dispatch of the aircrafi carrier Queen Elizabeth and its strike group to Japan and the Indo-Pacific later in the year, according to the Japanese Foreign Ministry. “The deployment of the British aircraft carrier strike group to the Indo-Pacific symbolizes Britain's commitment to the region," Motegi was quoted by the ministry as telling Raab in their first face-to-face talks since August 2020. Motegi also hailed Britain's pronouncement of proactive engagement in the Indo-Pacific in its integrated review of foreign and defense policy released in March The two ministers shared "grave concerns" about China's unilateral attempts to change the status quo in regional waters such as the enforcement of a new security law allowing its coast guard ships to fire on foreign vessels in waters Beijing sees as its territory.
