ONE Championship made a successful return to action over the weekend, hosting back-to-back events in Shanghai, China behind closed doors.

ONE Hero Series 13 was held on Saturday, followed by ONE Hero Series 14 on Sunday.

"We at ONE Championship are delighted to once again host the world’s most exciting martial arts events," said Hua Fung Teh, group president of ONE Championship.

"I would like to personally thank all the fans for their continued support for our organization and our athletes. Shanghai served as the perfect backdrop for the prestigious ONE Hero Series, which aims to showcase the absolute best in rising young martial arts talent from China," he added.

The organization stressed that it is prioritizing the health and safety of everyone involved, "through meticulous planning and stringent execution."

"By enforcing strict safety and sanitary measures, we made sure to prioritize the health and well-being of everyone who made these back-to-back events a huge success," Hua said.

Last June 12, ONE Championship chairman Chatri Sityodtong said they are not rushing back to staging live events, as the safety of fans, athletes, and staff is their top priority.

Prior to last weekend’s events in Shanghai, the promotion’s last live event was in February when it held ONE: King of the Jungle in Singapore.

All of their subsequent events were cancelled due to the novel coronavirus pandemic.
