China's top shuttlers secured three places in the men's singles semifinals of the Indonesia Open Badminton Championship.

World number one Lin Dan and teammates Bao Chunlai and Chen Hong secured their places at the semi-finals after straight wins over their opponents at the quarterfinas on Friday.

Bao Chunlai got the first spot in the semifinals after an easy 15-5, 15-2 win over host player Sony Dwi Kuncoro.

Lin Dan worked harder to overcome Malaysian veteran Wong Choong Hann, who remains a tough player to beat in the tournament.

But Lin Dan was stronger in attacks and more accurate in the net to stay in control, trashing Wong 15-10, 15-7.

On another court, Chen Hong and Lee Chong Wei gave another interesting China-Malaysia battle.

The young Chinese has the patience to overcome aggressive play of Lee, putting the shuttlecock in places where the Malaysian didn't expect and striking with powerful smash when the opponent expected a rally.

Chen Hong trashed the battling Lee 15-11, 15-9 to secure a berth in the semis, where he will face compatriot Bao Chunlai on Saturday.

Host player Taufik Hidayat secured the last spot in semifinals after ending Malaysia's last hope Hafiz Hashim 15-12, 15-7.

The Olympic champion will play Lin Dan in the most awaited match for local fans at the crowded Bung Karno Indoor Stadium.
