Roger Federer said he would be happy for the Laver Cup to be played in China in the future, ahead of the tournament's third edition starting on Friday in Geneva.
After the inaugural Laver Cup contested between Team Europe and Team World was held in Prague in 2017, last year's tournament in Chicago drew sellout crowds as Federer and world number one Novak Djokovic helped Europe win 13-8.
"Why not... it's completely open and flexible, but you have got to ask the Laver Cup people," 20-times Grand Slam champion Federer told reporters on Thursday.
"I'm sure they're looking into it, where it's going to go for the next decade or so.
"China has been a good place for us players. The tournaments in Shanghai and Beijing, they've been big. It's growing there as well with all the tournaments that are coming now, also on the women side.
