Hosts China all-but sealed a place in the semi-finals of the Asia Women's Sevens as they won their opening matches in style in Guangzhou.

China began their campaign at Guangzhou University Town Sports Centre with a 49-0 demolition of South Korea.

Hong Kong were later despatched 42-7 by the Chinese side, who featured as a core team on the 2019 World Rugby Sevens Series.

China are top of Group A on six points, two in front of Sri Lanka and Hong Kong, who are chasing the second spot in the semi-finals.

Sri Lanka were 19-5 winners over South Korea but lost 27-7 to Hong Kong.

In Pool B, Kazakhstan are also in line to qualify for the last four after they beat Thailand 17-12 and the Philippines 34-5.

Thailand are second following a 33-0 victory over Singapore, who overcame the Philippines 20-19 to keep their hope of reaching the semi-finals alive.

The winner of the tournament will join New Zealand, the United States, Canada, Australia, Brazil, Britain and Kenya in the women's rugby sevens event at Tokyo 2020.
