Reigning World champion and title favourite P V Sindhu sailed into the pre-quarter-finals at the China Open Super 1000 tournament with a convincing straight-games victory over former Olympic gold medallist Li Xuerui, in Changzhou, on Wednesday.
India's top shuttler beat the Chinese 21-18, 21-12 in just 34 minutes to set up a clash with Thailand's Pornpawee Chochuwong.
Replicating her World Championships form, the Olympic silver medallist produced another strong performance to get the better of the 20th-ranked Chinese, who entered the match with a 3-3 record against the Indian.
Men's singles players Sai Praneeth and Parupalli Kashyap also progressed to the second round after notching contrasting opening-round wins.
Commonwealth Games bronze medallists Ashwini Ponnappa and N Sikki Reddy too found a place in the pre-quarter-finals after crossing the opening hurdle in the women's doubles.
