CHENGDU - China crushed Chile 8-0 to finish as the group leader with an unbeaten record at the International Table Tennis Federation (ITTF) Mixed Team World Cup on Tuesday.

Japan, South Korea and Germany are other undefeated teams after three group matches.

Facing debutant Chile, the defending champion showed its class from the outset. World No 1 mixed doubles duo Lin Shidong and Kuai Man overcame an early test before sweeping Chile's Nicolas Burgos and Paulina Vega 13-11, 11-3, 11-3.

"We had a good start, but they returned several excellent shots afterwards. Through our adjustment on serves and change of rhythm, we won the first game, which was quite crucial," commented Lin.

Home favorite Wang Manyu made light work of winning the women's singles duel against Daniela Ortega, 11-4, 11-4, 11-8.

"It was my first match in this year's tournament and also my first encounter with her. I just played at my level today," said Wang.
