U.S Secretary of State Antony Blinken will visit Tonga, New Zealand and Australia next week as the Biden administration shifts its Indo-Pacific strategy into overdrive in part to counter China’s growing influence in the region.

The State Department said Thursday that Blinken will dedicate a new U.S embassy in the Tongan capital of Nukualofa on 26 July before heading to Wellington, New Zealand, where he will attend the women’s World Cup match between the United States and the Netherlands.

Blinken will then have meetings with New Zealand officials and move on to Brisbane, Australia, for meetings with U.S. Defence Secretary Lloyd Austin and their Australian counterparts 28-29July.

The trip will be Blinken’s third to Asia in the past two months — following a visit to China last month and a visit to Indonesia for talks with Southeast Asian officials last week. And, it comes as Treasury Secretary Janet Yellen and climate envoy John Kerry have recently wrapped up their own trips to China.

Second gentleman Douglas Emhoff is currently in New Zealand for the World Cup and will be making a side trip to Samoa in the coming days.

Blinken’s travel was announced a week after the State Department notified Congress that it plans a massive increase in diplomatic personnel and spending for facilities at new U.S embassies in the Pacific islands.

The boost in the U.S presence in the Pacific is in response to China’s increasing assertiveness there.

The update to Congress, which was obtained by The Associated Press, pointed out that China has permanent diplomatic facilities in eight of the 12 Pacific island nations that the United States recognizes and said the United States needs to catch up.

The department told lawmakers that it envisions hiring up to 40 staffers over the next five years for each of four recently opened or soon-to-be-opened embassies in the Pacific.

Those are the embassy in Nuku’alofa; an embassy in Honiara, Solomon Islands, that opened in January; and planned embassies in Port Vila, Vanuatu, and Tarawa, Kiribati. Currently there are two temporary American staffers each in Honiara and Nuku’alofa.

At each of those posts, the department said, it will spend at least US$10 million for start-up, design and construction costs.
