For the mixed doubles, South Korea's Jang Woo-jin and Cha Hyo-sim will play together,... as will Yoo Eun-chong and Pak Sin-hyok.
The six-day event is set to take place in the city of Daejeon, south of Seoul.
This will mark the third time since 1991... that the two sides have formed joint teams for table tennis,... and the first time the North has competed in an event under the International Table Tennis Federation.
