South Korean President Roh Moo-hyun said Tuesday that South Korea's stance over expansion of United States Forces Korea (USFK)'s role is that the USFK can not get involved in disputes in Northeast Asian region without South Korea's consent.

Roh made this remark when he delivered a speech at an Air Force Academy commencement ceremony earlier Tuesday, according to a press release of the Presidential Office.

Roh's remark follows a report that the United States is adopting "strategic flexibility," under which US soldiers stationed in South Korea will be reshaped as "rapid deployment forces" to interfere in military conflicts in Northeast Asia.

"We will never compromise on this," Roh said.

It was the first time the South Korean president expressed his clearly standing over the sensitive issue since the US side raised the issue in last April's South Korean-US Future of the Alliance (FOTA) forum.

In accordance to the news strategy named Global Defense Review, Washington proposed to reorganize its troops in foreign countries to make them more flexible and more agile.

But South Korea showed very cautious attitude toward the expansion of US troops role, worrying it may weaken US-South Korean combined deterrent capabilities and arouse concern among neighboring countries.

It was reportedly that the two allies will discuss the issue of USFK's strategic flexibility in future.

Moreover, Roh reiterated his government will make efforts to regain full control over its military within a decade and make the South Korean military stronger in the speech.

Under current system, in event of war, the USFK will control over South Korean troops. Seoul and Washington agreed earlier to transfer such command right to South Korean side in future.
