South Korea transferred control of its forces to the U.S.-led U.N. command in 1950 that helped the country repel invading communists from the North during the Korean War.
The conflict ended in a 1953 truce, but control over the South's forces remained with an American general as chief of the U.N. command, or the South Korea-U.S. Combined Forces Command.
In 1994, South Korea regained peacetime control of its military, but the chief of U.S. forces in South Korea is still is to take over control during wartime.
In his Armed Forces Day speech early this month, South Korean President Roh Moo-hyun said the country's armed forces will develop into a "self-reliant military that has its own operational control."
On Wednesday, Roh's spokesman, Kim Man-soo, said Seoul "raised the issue of discussing wartime operational control" during a defense officials' meeting with Washington last month.
About 32,500 U.S. troops are stationed in South Korea as a deterrent against threats from the North, but the numbers are set to decline to about 24,500 in coming years as part of Washington's worldwide redeployment of its forces. About 5,000 of the troops have already left in recent years, many deployed to Iraq, reported AP.
