Japan has dispatched a Maritime Self-Defense Force flotilla on a deployment to 11 Indo-Pacific countries and one foreign territory as part of joint naval exercises with the United States and other countries undertaken to counter a more assertive China.

In the annual deployment that began last Monday and will run through Oct. 28, the MSDF fleet will make port calls in the Pacific island nations of the Solomon Islands, Tonga and Fiji for the first time, according to the Defense Ministry.

The fleet will also take part in the Rim of the Pacific (RIMPAC) exercise — the world's largest multinational naval exercise — the Pacific Vanguard exercise involving Australia, Japan, the United States and South Korea, and other drills, the ministry said.
