Olympic 110-meter hurdles champion Liu Xiang of China says he will race at the London Diamond League meeting two weeks before the Olympics.
Liu won gold at the 2004 Olympics in Athens. He pulled out of the 2008 Beijing Games because of an injury, but is the early favorite for the London Games that begin July 27.
Liu says the Aviva London Grand Prix on July 13 will be a "great opportunity to experience the conditions and atmosphere of the Olympic host city."
He says he's hoping for a "very strong performance" at the meet to complete his preparations for a "second Olympic gold medal."
