Four different Asian nations will be represented in the semi-finals of the women's singles at the International Table Tennis Federation German Open in Bremen but, unusually, China are not among them.

The world's dominant nation did not send their strongest team to this week's event at the ÖVB-Arena but will be disappointed nonetheless that their two remaining players each lost in today's quarter-finals.

It left players from Japan, South Korea, Singapore and Chinese Taipei standing heading into tomorrow's finale.

Wu Yang was ousted 4-2 by Japan's second seed Kasumi Ishikawa while Sun Yingsha lost by the same margin to Cheng I-ching of Chinese Taipei.

Singapore's top seed Feng Tianwei cruised through 4-0 against Jeon Jihee of South Korea elsewhere.

She will now face Suh Hyo-won, who edged an all South Korean clash with Yang Hae-un 4-3.

It continued a superb tournament for Suh after she knocked-out Japan's Asian champion Miu Hirano yesterday.

China's Ma Long won a battle of the Olympic medallists in the men's singles last-16 after beating Japan's Jun Mizutani 4-0.

He then won 4-1 against home favourite Timo Boll in the quarter-final.

The scoreline did not reflect the closeness of the match as the reigning world and Olympic champion came from 10-5 down in the final set to secure the win.

Patrick Franziska, who beat German top seed Dmitrij Ovtcharov yesterday, kept the home flag flying by overcoming Marcos Freitas of Portugal 4-2 and then Kristian Karlsson of Sweden 4-1 today.

He will next face China's Xu Xin, a 4-2 quarter-final winner against Simon Gauzy of France.

Wong Chun Ting of Hong Kong completed the semi-final line-up with a 4-1 success against Sweden's Mattias Karlsson, who had earlier surprised Japan's fourth seed Koki Niwa 4-1.
