WELLINGTON: Japanese warships docked in New Zealand ‘s capital Friday for the first time in almost 90 years amid efforts by Tokyo to deepen its strategic ties in the South Pacific Ocean.

Two destroyers with more than 500 crew on board sailed into Wellington harbor accompanied by the New Zealand navy ship HMNZS Canterbury. The JS Ise and destroyer JS Suzunami were on an Indo-Pacific deployment and arrived from Sydney, where Japan’s military took part this month in war games involving New Zealand, Australia and other countries.

The Wellington visit was a ceremonial one, but it came as Japan, whose only treaty ally is the United States, has increasingly sought to deepen bilateral military cooperation amid ongoing regional tensions.

“Our defense force are developing cooperative work, not only with New Zealand and Australia but also many Pacific Island countries,” Japan’s envoy to Wellington, Makoto Osawa, told reporters Friday. “Our main goal is the free and open Indo-Pacific.”

The ambassador’s remarks followed the announcement Tuesday by Australia’s government that Japanese firm Mitsubishi Heavy Industries had won the bid for a contract to build Australian warships, beating out a German firm. While officials in Canberra said the Japanese proposal was the best and cheapest, they also hailed it as the biggest defense industry agreement between the countries.
