China's Wu Peng used an impressive finishing kick to beat Michael Phelps in the 200-meter butterfly at the Charlotte UltraSwim meet in North Carolina on Saturday.

Wu passed both Phelps and Sebastien Rousseau and touched the wall to win in a time of one minute, 56.69 seconds. American Phelps finished second in 1:56.87 while South Africa's Rousseau was third in 1:57.54.

Wu will be chasing his first Olympic medal in the 200 butterfly at the London Games.

"I was satisfied with my performance," Wu said. "If I just get any medal in London, I will be happy. Everyone wants to beat Michael because Michael is the fastest swimmer in the world. But I really just want to be (in the) top three."

Wu broke Phelps' long winning streak in the 200 butterfly last year.

Phelps took part in just two races at the Charlotte meet, also placing second in the 200 freestyle. "I know this is not the Olympic trials. This is not the Olympic Games," 14-time Olympic gold medalist said.

"It's a stepping stone heading in right direction for the end result. You've heard me say that so many times, but that's the truth. These are little things along the way to really see what I need to improve on."
