The U.S., Japan and South Korea held drills in the disputed East China Sea.

China expresses ‘serious concerns’ over exercise in disputed waters

ABOARD THE USS THEODORE ROOSEVELT — A U.S. carrier strike group led by the USS Theodore Roosevelt has held a two-day joint exercise with its allies Japan and South Korea as U.S. President Joe Biden met for talks with leaders from Japan and the Philippines at the White House. The military and diplomatic maneuvers are meant to strengthen the partners’ solidarity in the face of what they see as China’s aggressive military actions in the region.

A number of U.S. and South Korean guided missile destroyers and a Japanese warship joined the drills in the disputed East China Sea, where worries about China’s territorial claims are rising. The Associated Press was one of several news organizations allowed a front-row look at the drills.

Rear Adm. Christopher Alexander, commander of Carrier Strike Group Nine, said the three nations conducted undersea warfare exercises, maritime interdiction operations, search and rescue drills and work focused on communication and data sharing. He told journalists Thursday on the Roosevelt that these drills would help improve communication among the United States and its allies and “better prepare us for a crisis in the region.”

In Beijing, the Chinese Foreign Ministry said its director-general of Asian affairs had met with a top Japanese Embassy official on Friday and expressed “serious concern and strong dissatisfaction” about Japan’s “negative moves” during Prime Minister Fumio Kishida’s meetings in Washington with Biden and Philippine President Ferdinand Marcos Jr.

That followed earlier Chinese statements that accused the U.S. and Japan of smearing China and urged them to stop undermining regional peace and stability, while saying China will “resolutely defend” its security and development interests.
