"Athletes must not become victims of the policies of their governments," Rogge said in a joint interview with German television channel ARD and Berlin radio station SFB when asked whether athletes from countries suspected of supporting terrorism should be barred from entering the Olympic Games.
"What their governments do is that government's problem," he added. "We will welcome the athletes of the world as long as sport in their country is practised in harmony with our values."
Rogge repeated that next February's Winter Olympics in Salt Lake City should take place despite the attacks in the United States on September 11.
"The organisers and the American authorities have assured us that security will be taken care of," he said. "Therefore we see no reason to postpone or call off the Games. The Games will take place."
Rogge also said a likely German bid for the 2012 Summer Games should be "very strong".
"The fundamental advantages of Germany are known worldwide," said Rogge, adding he expected strong bids from other countries.
The German Olympic Committee (NOK) will rule on a German bid for the 2012 Games in November.
