SYDNEY - Favorites China and Australia moved closer to the semifinals of the FIBA Women's Basketball Asia Cup after recording powerful victories here on Tuesday

China produced a defensive masterpiece in an 80-46 thrashing of New Zealand to remain unbeaten in the tournament, while Australia used their height advantage to crush Chinese Taipei 91-45.

New Zealand, buoyed by an upset win over 12-time Asia Cup winners South Korea on Monday, were suffocated by China's gritty defense in the third quarter and went scoreless for almost 7 minutes until a short hook by Stella Beck with 50 seconds left.

China's towering center Han Xu continued her strong form with 17 points and 13 rebounds. Li Meng and Pan Zhenqi each had 10 pointes for China. Grace Hunter (10 points) was the only New Zealand player to reach double figures.

"I think we always focus on teamwork and for today, we performed much better in terms of defense than our first game," Han said.

China are the only unbeaten team in Group A and a win over South Korea on Wednesday will secure them a spot in the semifinals.

"We know their style, they play really fast and have good shooters. But we'll be ready tomorrow," China coach Zheng Wei said about their clash with South Korea.

New Zealand head coach Guy Molloy made a trio of changes to his starting line-up, electing to rest leading scorer Penina Davidson and Tahlia Tupaea for the entire game in favor of Josie Trousdell (nee Stockill) and Esra McGoldrick - while also promoting Tayla Dalton off the bench.

China held the Kiwis to seven points in the second quarter on 25 percent shooting as the Chinese built up the score to 33-20 at the halftime.
