World champions Germany were held to a 1-1 draw by Belgium on Wednesday but stay on course for a semi-final spot at the Olympic hockey tournament.

The Germany, who began the tournament with a 4-1 defeat of hosts China, took the lead in the 18th minute through Matthias Witthaus but were pegged back five minutes later by Cedric Charlier.

It was a first point for Belgium in Pool A following a 4-2 defeat to Spain.

Meanwhile South Korea bounced back from a 3-1 defeat to New Zealand by downing China 5-2.

Pool A saw defending Olympic champions Australia demolish South Africa 10-0, with Eli Matheson bagging three and Jamie Dwyer and David Guest two apiece.

It was a second big win for the highly-fancied Australians who had beaten Canada 6-1 in their opening match.

For the South Africans, it was another heavy defeat after being crushed 5-0 by the Netherlands, one of the favourites, in their opening game.

Pakistan, who were beaten 4-2 by Britain in their first game, came from behind to beat Canada 3-1 with goals from Muhammed Imran, Shafqat Rasool and Muhammed Saqlain.
