S. Korea, U.S., and Japan join against N. Korea threat

SEOUL, South Korea - South Korea, the United States and Japan will hold their first joint military training next month focused on cooperating to detect signs of missile launches from North Korea and trace missile trajectories, a Seoul defense official said Monday.

The drills, set for around June 28, will be held on the sidelines of biennial multinational naval exercises scheduled for waters off Hawaii from June to August, which the three countries regularly attend, the official said. The official spoke on condition of anonymity, citing department rules.

North Korea tries to show its military might

The trilateral drills will involve Aegis-equipped ships from the three countries, but they will not involve missile-interception training, the official said. The three countries have held joint search-and-rescue drills in the past.

The training follows a 2014 intelligence-gathering pact among the three countries, designed to better cope with North Korea's increasing nuclear and missile threats. It was the first such agreement among the three countries. An international standoff over North Korea has recently deepened after Pyongyang carried out its fourth nuclear test in January and a failed long-range rocket launch in February.

Washington regularly holds military drills with South Korea and Japan - which together host about 80,000 American troops - and shares intelligence with them on a bilateral level. But Seoul and Tokyo don't, largely a result of lingering public resentments in South Korea against Japan over its 1910-1945 colonial rule of the Korean Peninsula.

The Korean Peninsula was divided into a U.S.-backed South Korea and a Soviet-supported, socialist North Korea at the end of the Japanese occupation. The two Koreas fought a devastating three-year war in the early 1950s that ended with an armistice, not a peace treaty.

A look at growing up inside North Korea

Earlier this month, North Korean leader Kim Jong-un said heis ready to improve ties with "hostile" nations, and called for more talks with rival South Korea to reduce misunderstanding and distrust between them. He also urged the United States to stay away from inter-Korean issues.

"Our republic is a responsible nuclear state that, as we made clear before, will not use nuclear weapons first unless aggressive hostile forces use nuclear weapons to invade on our sovereignty," Kim said in a speech during a critical party congress in Pyongyang.

He said that North Korea "will sincerely fulfill its duties for the non-proliferation of nuclear weapons and work to realize the denuclearization of the world."

The North is ready to improve and normalize ties with countries hostile to it if they respect its sovereignty and approach it in a friendly manner, Kim said.

Despite the talks about more diplomatic activity, Kim also made it clear that the North has no plans to discard its "byongjin" policy of simultaneously developing its nuclear weapons and its domestic economy.
