China's Wang Yihan won the women's singles badminton world title on Sunday beating Taiwan's Cheng Shao Chieh 21-15, 21-10.
After Olympic champion Lin Dan of China earlier won the men's singles title, Wang, the second-seeded former All-England champion, overcame surprise finalist Cheng, the seventh seeded Taiwanese, 21-15, 21-10.
Wang made an apprehensive start, trailing 9-12, but once she began to feel more comfortable, dominated most of the rallies with her longer reach, greater height, steeper drops and superior power.
She maintained the pressure on Cheng with these weapons, preventing the Taiwanese from hustling in the way she had done when she beat the top-seeded Wang Shixian.
The triumph underlined the fine recovery that Wang has made since a lumbar injury prevented her from playing at the All-England championships in March.
It also gave China its third world title of the day and kept it in with a chance of becoming the first nation successfully to defend all five world titles. The opening match saw Wang Xiaoli and Yu Yang win the women's doubles.
