U.S. and Japan Announce Steps to Strengthen Their Military Ties

The top diplomatic and defense officials from the United States and Japan announced on Sunday that their nations would take concrete steps to bolster their military alliance because of the growing threat from China in the region.

Those steps include establishing joint forces that would answer to the American commander in the Indo-Pacific, according to a statement issued by the two governments’ top officials and the committee that they oversaw. They also call for increasing co-production of air-to-air missiles and air defense interceptor missiles.

The statement framed these changes in the alliance relationship mainly as a response to aggressive moves by China in East Asia. The statement focused on China’s actions in the East China Sea, South China Sea and beyond while also mentioning hostile activity by Russia and North Korea.

The governments reaffirmed the importance of the mutual-defense clause in their treaty because of the “increasingly severe security environment caused by recent moves of regional actors,” they said.

One of the top issues cited was the East China Sea, which Japan and China both claim part of. The American and Japanese senior officials said their governments reiterated their strong opposition to China’s “intensifying attempts to unilaterally change the status quo by force or coercion.”

The U.S. secretary of state, Antony J. Blinken, and the U.S. defense secretary, Lloyd J. Austin III, were in Tokyo on Sunday to meet with their Japanese counterparts in what is commonly called a 2+2 dialogue.
