Vu Thi Trang reached the semi-finals of the Badminton World Federation (BWF) Vietnam Open to keep alive hopes of a home winner.

The 25-year-old fourth seed came through her last eight clash on quarter finals day at the Nguyen Du Stadium in Ho Chi Minh City.

She proved too strong for Pai Yu-po of Chinese Taipei and came through 21-19, 21-12.

Vu, a bronze medallist at the 2010 Youth Olympic Games in Singapore, will now play second seed Hanna Ramadini of Indonesia in the semi-finals.

All of the top four seeds made it through with Ramadini defeating another Chinese Taipei player in Chen Hsiao-huan, 14-21, 21-17, 21-10.

Japan's top seed Sayaka Takahashi continued the bad day for Chinese Taipei by beating Chen Su-yu 21-13, 21-18.

She will now meet third seed Dinar Dyah Ayustine of Indonesia, an 18-21, 21-15, 21-8 winner over Gadde Ruthvika Shivani of India.

In the men's draw, Thailand's Khosit Phetpradab came from behind to progress to the last four.

The third seed, the top ranked player left in the draw, knocked out Indonesia's Shesar Hiren Rhustavito 19-21, 21-13, 21-7.

His reward is a clash with Japan's Kodai Naraoka, a 21-17, 21-23, 21-10 winner over India's Lakshya Sen.

An all-Thai final remains a possibility after Suppanyu Avihingsanon beat compatriot Thammasin Sitthikom 10-21, 21-19, 21-16 to go through.

He will play Goh Giap Chin, who won an all-Malaysian affair against Liew Daren 21-18, 13-21, 21-13.

The semi-finals will be played tomorrow.
