China's Li Haotong shot a bogey-free 8-under 64 on Sunday to win the China Open for his first European Tour title.
The 20-year-old Li, who began the day two shots behind leaders Felipe Aguilar of Chile and Denmark's Lucas Bjerregaard, finished three strokes clear of runner-up Aguilar at 22-under 266.
Aguilar, who shot a 69, held a two-shot lead at the turn but a double bogey on the par-3 16th dashed his title hopes.
Li missed the cut at last week's Shenzhen International, the first of back-to-back European Tour events in China.
"I just tried to relax myself and I'm really happy to hold the trophy here," Li said. "The start of this year has given me a lot of hard times. Even though I worked hard I still played badly, especially last week. I worked hard there and couldn't control my ball."
Bjerregaard shot a 70 to finish in a three-way tie for third with Marcel Siem of Germany and England's Richard Bland.
Peter Hanson, Scott Hend and Richie Ramsay followed at 17 under, a shot ahead of David Lipsky, Alex Noren, Borja Virto Astudillo and Fabrizio Zanotti.
