ONE: Pinnacle of Power is set for June 16 in Beijing and will feature two title fights. In the co-main event, regular champion Adriano Moraes faces interim champion Geje Eustaquio in a flyweight unification bout.
The main event was previously announced for a card in Shanghai, but has now been moved to Beijing. It pits strawweight champion Xiong Jing Nan against Argentinian challenger Laura Balin in what will be the first title defends for the Chinese fighter.
Moraes (17-2) and Eustaquio (10-6) first faced off in 2014 in a fight which had the inaugural flyweight strap on the line. The Brazilian won by submission and has remained the dominant force in the division ever since, although he was temporarily parted from the belt after a split-decision loss to Kairat Akhmetov.
Coincidentally Eustaquio also has a split-decision loss to Akhmetov on his record but, like Moraes, he successfully outpointed the Kazakh flyweight in the rematch.
ONE: Pinnacle of Power will take place at the Olympic Sports Centre in Beijing and is one of four events the promotion currently has booked for China between now and the end of the year.
