International Olympic Committee (IOC) president Jacques Rogge has praised China's preparation for the 2008 Olympic Games in Beijing.

"It's always a great challenge to organize an Olympic Games because it's a huge, huge organization, a very complex one. Definitely, our Chinese friends have everything in hands, and the yare doing extremely well," Rogge told Xinhua after meeting with United Nations Environment Program officials in Nairobi on Tuesday.

Rogge specially commended the Beijing Organizing Committee of the 2008 Olympic Games, saying "it's a very good organizing committee, and we will work closely with them."

"I was in Beijing a month ago. I'll be going to Beijing twice or maybe three times more this year," said Rogge.

Rogge arrived in Nairobi Monday for a four-day visit to Kenya, his first trip to Africa since being elected as IOC president in 2001.

He is expected to officially open the National Olympic Committee of Kenya Headquarters in Nairobi on Wednesday.
