SEOUL, Feb. 10-- South Korea agreed to return more remains of Chinese soldiers killed in the 1950-53 Korean War after the two countries held working consultations here on Tuesday afternoon, sources from the Chinese Civil Affairs Ministry said.

South Korea handed over to China the remains of 437 Chinese volunteer soldiers killed in the war in March 2014.

South Korea has excavated 68 more remains of the Chinese volunteer soldiers and other belongings since then.

China and South Korea have decided to hold the transfer ceremony of these remains late in March, just before the traditional Chinese Tomb-sweeping Day.

The Chinese People's Volunteers (CPV) fought side by side with the Korean people's army of the Democratic People's Republic of Korea in the Korean War against the South Korean army and U.S.-led UN forces.

Tens of thousands of CPV soldiers died on the Korean Peninsula during the war that ended in armistice.
