Zheng Qinwen beat Donna Vekic in straight sets to win Olympic women's singles gold for China in Paris.
Zheng, who lost in the Australian Open final in January, was a 6-2 6-3 winner on Court Philippe Chatrier at Roland Garros.
The 21-year-old raced into a 3-0 lead in the first set against Croatian world number 21 Vekic and converted her first set point, also on the Vekic serve.
The second set was a much tighter affair, but Zheng - ranked seventh in the world - broke in a pivotal eighth game before serving out the match.
Vekic, 28, was appearing in the gold medal match less than a month after narrowly missing out on the Wimbledon final, losing her semi-final to Jasmine Paolini in a deciding set tie-break.
Lorenzo Musetti of Italy will face Canada's Felix Auger-Aliassime for men's singles bronze in the final match at Roland Garros on Saturday.
