P. V. Sindhu wins 2016 Chinese Open

P. V. Sindhu has won the Chinese Open BWF Super Series final, against Sun Yu of China, with the final score reading 21–11, 17–21, 21–11.

Sindhu was agile, nimble and mostly attacking with quite a few hard smashes to surprise Sun Yu and got to a 11-5 lead in the first 8 minutes of the game.
 

Sindhu's judgement was precise in the first game which saw only one rally, which Sun Yu won. For the most part, both were in attack mode, with Sindhu prevailing over Sun Yu.

The second set was a tight contest, till the score was reading 17-17, with one interesting long rally for the 12th point with Sun Yu winning it. Both were in their thinking mode with a few intelligent drops and placements by both the players. Sun Yu won the second set with some aggressive body smashes to boot, enabled by Sindhu's somewhat defensive play in the latter part of the 2nd set.

The third game saw Sun Yu hitting beyond the line a few times making unforced errors, while Sindhu was on her own aggressive self, winning 21-11 comfortably.

P. V. Sindhu and Saina Nehwal are the only non-chinese who have won the China Open badminton tournament,  since the first tournament in 1986.

Wong Mew Choo, who won the women's singles title in 2007 is Chinese too, even though from Malaysia.
 

So, essentially, only India has won the Chinese open other than the Chinese.
