South Korea will return to China the remains of 28 Chinese soldiers who fought during the Korean War amid high tensions with the country over the installment of the THAAD antimissile system.
The Defense Ministry said the remains exhumed last year were placed in coffins in a rite in Incheon on Monday.
A ministry official said that the ministry decided to send back the remains based on humanitarian spirit stipulated in the Geneva Convention even if military exchanges and cooperation between the two countries are going through a difficult period.
The remains will be sent back China in a ceremony at Incheon International Airport on Wednesday.
The ministry has been exhuming the remains of Chinese soldiers who fought in the Korean War since 2014. The remains of 541 Chinese soldiers have been repatriated on three occasions.
