SEOUL - THE US military has proposed holding a major troop-landing exercise involving more than 10,000 US and South Korean marines in Nov, according to a report on Monday.

It was put forward by General Walter Sharp, who commands 28,500 US troops here, to demonstrate joint military capability in the face of communist North Korea, the Yonhap news agency said.

However Seoul is lukewarm as it believes a large-scale drill could further chill relations with the reclusive regime in Pyongyang, which have worsened since President Lee Myung-Bak took power in Feb, it added.

A South Korean defence ministry spokesman said both sides are yet to set a date for an exercise or the number of troops to be involved.

Yonhap said General Sharp made the proposal during a visit in July to South Korea's marine corps command, and had already ordered the temporary redeployment of a Marine unit from Japan for the exercise.

'General Sharp said the countries needed to demonstrate to North Korea that their combined forces are well capable of conducting such a large-scale amphibious operation,' a military source was quoted by Yonhap as saying.

The North routinely criticises exercises involving US and South Korean troops as a prelude to invasion, while the US and South Korea say they are purely defensive.

The two Koreas have remained technically at war since their 1950-1953 war ended only with an armistice and not a peace pact. -- AFP
