LONDON - China's Wang Hao, seeded No 2, comfortably booked a seat in the semifinal after beating Seiya Kishikawa in four straight sets (11-4, 11-5, 11-3, 11-5), dashing Japan's last hope of claiming an Olympic medal in table tennis singles events in London.

Wang, twice Olympic silver medalist, said he had prepared for a hard game against Kishikawa but it turned out all right.

Wang will face Chuang Chih-Yuan of Chinese Taipei, No 5 seed, in the semifinal. Chuang entered the semifinal after beating Romania's Adrian Crisan 4-0.
