In a statement late Monday, the Latin American sports body said it had "complete confidence" the Peruvian Olympic Committee would deliver the Pan American Games, an Olympic-style event held every four years. It said it would visit Lima soon on a fact-finding mission.
A Peruvian legislator alleged last week that the committee had misappropriated $500,000. President Jose Quinones has denied the allegation, but offered to resign.
Quinones said in a radio interview Monday that Peru was "ready and capable" of organizing the event. Peru is to spend about $700 million on the games.
The 2015 Pan American Games will be held in Toronto.
