BEIJING, March 29 -- A Il-76 transportation plane arrived in the Republic of Korea (ROK) Tuesday to bring back the remains of Chinese soldiers killed in the 1950-1953 Korean War, according to military sources.

The plane will return to Taoxian International Airport, Shenyang, on March 31, and will be escorted by two Chinese fighter jets once it enters Chinese airspace, said Shen Jinke, People's Liberation Army (PLA) Air Force spokesperson.

The spokesperson didn't say how many Chinese soldiers' remains will be returned this time.

The Chinese People's Volunteers (CPV) fought alongside the Democratic People's Republic of Korea army in the Korean War against the South Korean army and U.S.-led UN forces between 1950 and 1953.
