The International Olympic Committee on Wednesday announced a sweeping new clampdown on doping by doubling the pre-Games testing budget for Rio de Janeiro and further expanding re-testing of athletes from the 2008 and 2012 Olympics.

Special focus will be on Russia, Mexico and Kenya where, the IOC said, testing programs were “non-compliant.”

The IOC and the World Anti-Doping Agency will also “target medalists from both Olympic Games for possible re-analysis,” the IOC Executive Board said after discussing the issue.

“For legal reasons the IOC cannot give more detailed information on the cases at this point,” The IOC told that asked whether riders or horses were being re-tested. Several jumper horses and onen dressage horse tested positive for illegal substances in 2008 but no positive results were reported at the London Games.

The IOC announced last month that dozens of athletes at the Beijing and London Olympics whose samples had been re-tested were found to be positive. Testing of Russian athletes at the 2014 Sochi winter Games was also reported to have been tampered with.

“The IOC will not hesitate to punish anyone within its reach responsible for using or providing doping products or methods, including officials, coaches and other members of the athlete’s entourage,” the IOC said.

A meeting of Olympic stake holders will be held later this month to coordinate and harmonize the approach among international sports federations to “take the first decision of the eligibility of athletes with respect to qualification for and participation in” the Rio Olympic Games.

“The discussion will have to address the difficult decision between collective responsibility and individual justice,” the IOC said.

An Olympic summit in October will evaluate and review the entire doping program and measures taken at Rio, it said, and will continue to push for all testing to be independent of sports organizations set up a new body to harmonize national and international testing.
