China reach hockey semis

China have reached the semi-finals of the Olympic women's field hockey for the first time after beating Group A opponents Spain 3-0.

It was their third consecutive victory, although coach Kim Changback was not impressed by the overall performance.

"They all want to score goals instead of communicating with each other. If they play as a team they can do much better." Kim said.

The Netherlands also made the last four with a 4-1 win over Germany in Group B.

Also in Group B, second-placed South Korea saw off South Africa, who have yet to win a match, 3-0.
