MACAO - China has secured both titles in advance at the ITTF World Cup as they booked all the four final spots here on Saturday, with Ma Long sweeping Wang Chuqin 4-0 in the men's singles semifinals.

The match between world No. 1 Wang and veteran Ma was highly-anticipated, but the showdown turned into a lopsided one as Ma made short work of Wang 11-9, 12-10, 11-6, 14-12, which was beyond Ma's imagination.

"He is a bitter rival for me in recent years. I didn't expect that result. I was relaxed during the play and had many quality shots that put pressure on him."

Ma takes on compatriot Lin Gaoyuan in the final, as the world No 8 eliminated Japan's Tomokazu Harimoto in four straight games.

Sun Yingsha and Chen Meng also provided a Chinese derby in the women's draw, as Sun came from 1-0 down to get the better of her teammate 4-2, setting up a clash with Wang Manyu, who knocked out Miwa Harimoto by the same scoreline.
