Don't expect to see Liu back on track in 2013 (2)

The Shanghai Diamond League event, which will take place in the Shanghai Stadium on May 18, has so far attracted four Olympic champions and three world record holders among an array of international track and field stars.

Sprint hurdler Aries Merritt tops a list that includes world 100m champion and Olympic silver medalist Yohan Blake, world and Olympic 400m champion Kirani James, world junior and Olympic javelin champion Keshorn Walcott, and pole vault legend Yelena Isinbayeva.

Merritt will return to the meet in 2013 hoping to make amends after finishing fourth a year ago in a 110m hurdles contest that saw Liu claim victory.

Merritt will face Xie Wenjun, China's latest hurdling hope, in Shanghai.

Tipped by some as the new Liu, Xie lowered his personal best in the 110m hurdles to 13.34 sec in the Olympic semifinals in August and made a breakthrough earlier this year when he finished third over the 60m hurdles at the British Athletics Grand Prix in Birmingham in 7.60.

The 2013 Shanghai Diamond League meeting will feature 16 events, nine for men (200m, 400m, 1,500m, 110m hurdles, 3,000m steeplechase, high jump, long jump, discus and javelin) and seven for women (100m, 800m, 5,000m, 400m hurdles, pole vault, triple jump and shot put).
