The United States will likely play a role in the International Olympic Committee's new drug-testing agency, set to be established in Switzerland Wednesday.

But that role could be limited to only a few years under a proposal suggested by the man expected to lead the World Anti-Doping Agency, IOC Vice President Dick Pound of Canada."I certainly don't think the United States or any other government has an automatic place," Pound said.

Instead, he said government participation could be limited to those countries hosting future Games, such as the 2002 Winter Games in Salt Lake City.

A decision won't be made until the IOC members, sports officials, athletes and others who serve on the agency's board meet for the first time, probably in December.

The new agency has been criticized by Gen. Barry McCaffrey, the U.S. drug czar, as being too closely tied to the IOC. McCaffrey has said the Olympic leaders aren't fit to police performance-enhancing drug abuse by athletes.

He has tried to rally support from other world leaders for his position, but recently, the drug-testing agency was endorsed by the European Union. McCaffrey is reportedly headed to Australia to make his case there.

Pound's announcement earlier this week that he will head the agency for at least a few years raised new concerns with McCaffrey about the IOC's control over drug testing.

Pound, though, said that concern is not warranted. "This is an independent agency not under anybody's control, least of all the IOC's," he said.

The IOC is the primary source of funding for the agency, contributing $25 million.
