The Chinese fighter, who came second to France’s Estelle Mossely in the lightweight division at last year’s Olympic Games, triumphed 3-2 over the 2014 world silver medallist.

Awaiting her in the last eight is home favourite Vy Vuong Thi, who eased to a unanimous points victory over Indonesia’s Christina Marwan Jembay at the Nguyen Du Indoor Stadium.

In the same weight division, India’s Sonia Lather defeated Japan’s Kana Kurogi 5-0.

China also had success in the light welterweight and light heavyweight categories today through Dou Dan and Yang Xiaoli respectively.

Dou stopped Taiwanese opponent Lin Lee Wei Hsien in the third round of their contest, while Yang beat India’s Pooja Rani in a unanimous verdict.  

There was one defeat for China today, however, with flyweight Chang Yuan losing 4-1 to Kazakhstan’s Nazym Kyzaibay.

Hosts Vietnam had a successful day as they won the other two bouts in which they were represented.

Flyweight Tam Nguyen Thi beat Thailand’s Chuthamat Raksat 5-0, while welterweight Linh Tran Thi won by the same scoreline against South Korea’s Kim Shinhyeong.

Action in Ho Chi Minh City is due to continue tomorrow.

The competition is the eighth edition of the event first held in Thailand's capital Bangkok in 2001.
