Britain has announced that it will permanently deploy two warships in Asian waters after its Queen Elizabeth aircraft carrier and escort ships sail to Japan in September through seas where China is vying for influence with the United States and Japan. Plans for the high-profile visit by the carrier strike group come as the UK deepens security ties with Tokyo, which has expressed growing alarm in recent months over China’s territorial ambitions in the region, including Taiwan. “Following on from the strike group’s inaugural deployment, the United Kingdom will permanently assign two ships in the region from later this year,” Britain’s defence minister, Ben Wallace, said in a joint announcement on Tuesday in Tokyo with his Japanese counterpart, Nobuo Kishi.
