Japan plans to send largest warship to South China Sea

Japan plans to dispatch its largest warship on a three-month tour through the South China Sea beginning in May, three sources said, in its biggest show of naval force in the region since World War Two, Reuters has reported.

China claims almost all the disputed waters and its growing military presence has fueled concern in Japan and the West, with the United States holding regular air and naval patrols to ensure freedom of navigation.

The Izumo helicopter carrier, commissioned only two years ago, will make stops in Singapore, Indonesia, the Philippines and Sri Lanka before joining the Malabar joint naval exercise with Indian and U.S. naval vessels in the Indian Ocean in July.

It will return to Japan in August, the sources said.

“The aim is to test the capability of the Izumo by sending it out on an extended mission,” said one of the sources who have knowledge of the plan. “It will train with the U.S. Navy in the South China Sea,” he added, asking not to be identified because he is not authorized to talk to the media.

A spokesman for Japan’s Maritime Self Defense Force declined to comment.

Taiwan, Malaysia, Vietnam, the Philippines and Brunei also claim parts of the sea which has rich fishing grounds, oil and gas deposits and through which around $5 trillion of global sea-borne trade passes each year.

Japan does not have any claim to the waters, but has a separate maritime dispute with China in the East China Sea.

Japan wants to invite Philippine President Rodrigo Duterte, who has pushed ties with China in recent months as he has criticized the old alliance with the United States, to visit the Izumo when it visits Subic Bay, about 100 km (62 miles) west of Manila, another of the sources said.

Asked during a news conference about his view on the warship visit, Duterte said, without elaborating, “I have invited all of them.”
