The Korean idol groups JYJ and EXO will perform in the opening ceremony of the Incheon Asian Games on Sept. 19, their agencies said. It is the first time that the two groups will share the same stage.

JYJ, which has served as the promotional ambassador for the event since February last year, is to sing “Only One,” the theme song for the Incheon Asian Games, at a pre-opening ceremony.

EXO is scheduled to sing its hit song during the opening ceremony along with other popular Korean singers including Big Bang, Psy and CNBLUE.

The encounter between EXO and JYJ is gaining attention as it is the first time in five years for JYJ to meet EXO members, who are managed by their former agency.

JYJ and SM Entertainment, EXO’s current agency and JYJ’s former agency, went through a prolonged legal dispute regarding JYJ members’ exclusive contract.

The members of JYJ, Jaejoong, Yoochun and Junsu, declared their independence from SM Entertainment in 2009 when they were in the group TVXQ. The legal dispute between the members and agency lasted about five years, according to local reports.

Following the wrangling, JYJ and singers from SM Entertainment have avoided any official encounters together.
