First London gold goes to China
Yi finished with the result of 502.9 points at The Royal Artillery Barracks in the British capital.
Poland's Sylwia Bogacka took the silver medal with 502.2 points, while the bronze went to another Chinese representative, Yu Dan, who scored 501.5 points.
The best among the Russians was Daria Vdovina, who finished in eighth spot with 498.5.
Meanwhile, the country’s main hopeful in the event, Lubov Galkina, failed to make it into the finals.
"I wouldn’t say that this result is such a huge sensation. Galkina has got a good score of 396 points.” Igor Zolotarev, Russian Shooting Union’s sporting director, told Ves Sport. “In addition, she was a bit unlucky with her position as she was standing near an open door, through which the wind was blowing. But Lubov was still fighting.”
Galkina has one gold and two silver Olympic medals to her name, which the 39-year-old won in Athens 2004 and Beijing 2008.
