While tensions continue to rise in the South China Sea and the disputing governments nervously await a decision in the Philippines’ arbitration case against China, an important sideshow has arisen between Japan and Taiwan in the central Philippine Sea.
On 24 April Japan’s Coast Guard arrested a Taiwanese fishing vessel and its crew for fishing in waters that Japan claims are part of its 200-nautical mile ‘exclusive economic zone’ (EEZ) under the United Nations Convention on the Law of the Sea (UNCLOS). Japan’s EEZ claim is based on its control over two tiny rocks surrounded by a coral reef more than 1000 miles south of Tokyo. Although Japanese military patrols began chasing Taiwanese fishing boats away from the area two years ago, this was reportedly the first actual detention since 2012.
