China is golden once again at the World Aquatic Championships. China beat Olympic champions Australia with a world record finish to win the women's 4x100m medley relay on what was an eventful Saturday in the pool.

China battled it out with Australia all the way before Li Zhesi touched home in three minutes, 52.19 seconds to shatter the World Record mark of 3:52.69 set by the Aussies at the Beijing Olympics.

Australia also went under the old mark, settling for silver.

Germany took the bronze.
