SEOUL, March 10 (Reuters) - South Korea cannot stop Washington from redeploying some weapons stationed in the country, President Lee Jae Myung said on Tuesday, after reports that U.S. Patriot missile defence systems were being sent to the conflict in the Middle East.
Reports on shifting key U.S. military assets have sparked concern in Asia about the potential gaps in regional defences if Washington diverts ships and missiles currently used to deter military flexing by
China and North Korea to other theatres.
"It appears that there is controversy recently over U.S. Forces in Korea shipping some weapons, such as artillery batteries and air-defence weapons, out of the country," Lee said in a cabinet meeting, noting that while Seoul had expressed opposition, it was not in a position to make demands.
Lee insisted the removal of some U.S. weapons from the country "does not hinder deterrence strategy towards North Korea," noting South Korea's defence spending and conventional capabilities far exceeded those of North Korea.
South Korea hosts a major U.S. military presence in combined defence against nuclear-armed North Korea, with about 28,500 troops and surface-to-air defence systems, including the Patriot missile interceptors.
NORTH KOREA THREAT
South Korean Foreign Minister Cho Hyun said on Friday the U.S. and South Korean militaries were discussing the possible redeployment of some U.S. Patriot missile defence systems to be used in the conflict in the Middle East.
South Korean media reported some missile batteries had been shipped out of the Osan Air Base and were likely to be redeployed to U.S. military bases in Saudi Arabia and the United Arab Emirates, though South Korean authorities have not confirmed these reports.
U.S. Forces Korea also declined to comment on the relocation of military assets, citing operational security.
Reuters photographs at the Osan Air Base showed on Tuesday multiple mobile launchers on the tarmac that experts confirmed appeared to be Patriot PAC-2 and PAC-3 interceptors.
Military analysts said that while Lee was correct that South Korea is capable of deterring Pyongyang on its own, the presence of U.S. weapons underscored Washington's commitment to regional security.
"There is a risk that North Korea could miscalculate the relocation of some of these weapons as a pretext for low-level provocations to test the allies' defence posture," said Choi Gi-il, a military studies professor at Sangji University.
North Korean leader Kim Jong Un said in February he will focus on expanding his country's nuclear arsenal and called South Korea its "most hostile enemy," while he oversaw the test-firing of a missile on a naval destroyer last week.
DESTROYERS MOVED FROM JAPAN
U.S. and Israeli forces have been striking strategic targets inside Iran for more than a week, prompting analysts to warn that a prolonged conflict drawing Washington's focus away from Asia could threaten regional peace and stability.
Japan is also home to major U.S. military bases and two U.S. guided-missile destroyers homeported in the city of Yokosuka are currently deployed in the Arabian Sea to support the military operation against Iran, according to a report by the U.S. Naval Institute released on Monday.
The only U.S. carrier deployed in Asia is undergoing maintenance at Yokosuka.
The head of Japan's main opposition party raised concerns about the reports about the deployment of U.S. vessels based in Japan to the Middle East in parliament on Monday.
"Japan has not permitted the stationing of U.S. forces so they can sortie from those bases to fire missiles towards the Middle East," Junya Ogawa said, adding that they should be ensuring Japan's security and maintaining peace in East Asia.
Japan's government has not commented on the deployment of the U.S. vessels.
