China's military has called a British warship's recent passage through the Taiwan Strait a disruptive act of "intentional provocation" that "undermines peace and stability". The British Royal Navy says HMS Spey's patrol on Wednesday was part of a long-planned deployment and was in accordance with international law. The patrol - the first by a British naval vessel in four years - comes as a UK carrier strike group arrives in the region for a deployment that will last several months.
