Andy Murray showed no ill-effects from his recent injury when beating Italy's Andreas Seppi in straight sets in Beijing.
The 29-year-old picked up a thigh strain playing for Great Britain in their Davis Cup semi-final defeat to Argentina last month and has not played since downing Guido Pella in the reverse singles.
However, he took care of Seppi 6-2 7-5 at the China Open to set up a second-round clash with either Konstantin Kravchuk or Andrey Kuznetsov.
Fellow Brit Kyle Edmund is due to face Roberto Bautista in round two and, should he come through that, Murray might well be waiting in the next round.
The world number two looked impressive in the opening set, reeling off four successive games to take a 1-0 lead, but left it last to break his opponent in the second, taking Seppi's serve at 6-5 to close out the match.
The Scot was happy with how his body responded during the contest but feels he has a lot more to give this week in the Far East.
"I thought I did okay today considering I hadn't played much the last couple of weeks," he said. "I didn't arrive here until a couple of days ago. I thought I did okay. I think I can play better.
"But there was some good stuff in there. With each match I'll play better hopefully. It was the first time I practised on centre court, and played on centre court today. So I wasn't that used to the speed of the court and how it felt out there.
"But I felt okay, my body felt fine. There's no injuries, I felt healthy. I just need matches now."
