Peng Shuai makes Games appearance

Chinese tennis player Peng Shuai was on hand on Tuesday to watch China's Eileen Gu as she won gold in the Big Air competition in Beijing to put the host nation at the top of the medals table.

Peng, who could be seen in the stands wearing a black knit hat with the Olympic rings on them and a black coat with the Chinese flag, acknowledged a greeting from a journalist but declined to answer questions as she left the venue.

Peng's well-being became a matter of global concern when she appeared to allege on social media in November that a former Chinese vice premier, Zhang Gaoli, had sexually assaulted her in the past. After that post, which was quickly removed, she disappeared from public view for nearly three weeks.

International Olympic Committee President Thomas Bach visited with members of the group including Peng during the competition.

"I just met her, she was here sitting in the stadium," Bach told Reuters.

"She was among the athletes, and I had the opportunity to meet with a number of athletes from Switzerland and from Germany and the U.S.", he said.
