The event is scheduled to take place at Trigger Boxing Gym in HCMC on July 18.

Thao, 28, said Majiha will be his toughest rival to date. The 27-year-old Tanzania boxer has competed in 44 professional matches with 26 wins, 14 losses and four draws and won the WBA Pan African Bantamweight championship in 2018.

The "Vietnamese Mayweather" has pocketed 13 wins and one loss.

Thao is the first local fighter to make his name internationally. He shot to fame after defeating Indonesia's George Lumoly to become the first Vietnamese boxer to win a World Boxing Council (WBC) Asia title in November 2017.

But he couldn't compete in the 2018 WBC championship after sustaining injuries from a traffic accident. Since he couldn't defend his title, organizers decided to strip him of the title.
