Senior naval leaders from the United States, South Korea and Japan met in Seoul this week to strengthen maritime cooperation and coordinate responses to North Korea’s advancing missile and nuclear programs, according to the South’s navy.
Adm. Stephen Koehler, commander of the U.S. Pacific Fleet; Adm. Kim Kyung-ryul, South Korea’s chief of naval operations; and Adm. Saito Akira, chief of staff of Japan’s Maritime Self-Defense Force, discussed enhancing deterrence and response capabilities, the South Korean navy said in a news release Wednesday.
The talks follow a series of recent North Korean weapons tests that have raised tension in the region.
Pyongyang launched two strategic cruise missiles and three anti-ship missiles Sunday in what it described as an operational test of its destroyer, Choe Hyun. The North’s military also fired a Hwasong-11Ka surface-to-surface missile equipped with a cluster munition warhead during tests last week.
Kim hosted the two visiting admirals at his official residence after holding separate bilateral meetings with each.
During the U.S.-South Korea talks, Kim and Koehler discussed maritime security and ways to strengthen their joint defense posture, including expanding cooperation in fleet maintenance, repair and overhaul, according to South Korea’s navy.
In separate discussions between South Korea and Japan, Kim and Saito focused on increasing troop-level and personnel exchanges and on plans to resume joint search-and-rescue training.
Defense ministers from South Korea and Japan agreed in January to restart those drills after a nine-year hiatus. The exercises, first launched in 1999, were suspended in 2017 amid strained relations between the two countries.
The meetings happened as broader geopolitical tensions continue to shape the security environment for U.S. allies in Asia.
South Korean President Lee Jae Myung last month voiced opposition to the potential redeployment of U.S. Terminal High Altitude Area Defense, or THAAD, systems from the Korean Peninsula to the Middle East.
Japan and South Korea, both heavily dependent on imported energy, rely on maritime routes through the Strait of Hormuz, a critical chokepoint for global oil shipments where tensions have escalated in recent weeks.
Phillip Schrank, a foreign assistant professor at Chosun University’s Department of Political Science and Diplomacy, said he was not surprised the admirals did not directly address the Middle East conflict.
Those issues are “highly political” and will need to be resolved by decision makers like the secretaries of defense and state or a summit of leaders, he said by email Thursday.
“Trump can tweet about allies not helping him, but I think it would be politically impossible for Korea to get involved,” Schrank wrote.
Lee Ki-tae, a senior fellow at the Sejong Institute think tank, said the trilateral discussions were consistent with previous cooperation efforts rather than signaling a major strategic shift.
The talks “appear to have focused on responding to North Korea while maintaining a position that does not explicitly aim to contain China, along with strengthening [South Korea]-Japan maritime security cooperation,” Lee said by email Wednesday.
“Overall, the publicly released details remain within the expected range and do not suggest any major deviations from prior expectations,” he said.
South Korea’s navy did not release additional details about the meetings.
