China crushed the world record in the women's 800 free relay at the FINA World Championships, beating US as No. 1, followed by U.S. and Great Britain.

China's contingent of Yang Yu (1:55.47), Zhu Qian Wei (1:55.79), Liu Jing (1:56.09) and Pang Jiaying (1:54.73) cut two seconds from the Australian world record of 7:44.31 set at the 2008 Beijing Olympics.

The Australia team featured Stephanie Rice (1:56.60), Bronte Barratt (1:56.58), Kylie Palmer (1:55.22) and Linda Mackenzie (1:55.91).

Allison Schmitt nearly closed the distance in the final 50 meters for the U.S., but failed as the U.S. foursome of Dana Vollmer (1:55.29), Lacey Nymeyer (1:57.88), Ariana Kukors (1:55.18) and Schmitt (1:54.21) put together an American record time of 7:42.56 to take silver. That time beat the American record of 7:46.33 also set in Beijing.

Great Britain's team of Joanne Jackson (1:55.98), Jazmin Carlin (1:56.78), Caitlin McClatchey (1:56.42) and Rebecca Adlington (1:56.33) completed the podium with a 7:45.51.
