Russia have been banned from competing at the 2018 Winter Olympics.
Special permission will be granted to some athletes from the country and will compete under the name "Olympic Athlete from Russia."
After a long disciplinary committee meeting it was decided that further investigation would take place into a state-sponsored doping programme from the 2014 games.
IOC president Thomas Bach said: "This was an unprecedented attack on the integrity of the Olympic Games and sport."
"The IOC EB (executive board), after following due process, has issued proportional sanctions for this systemic manipulation while protecting the clean athletes."
"This should draw a line under this damaging episode and serve as a catalyst for a more effective anti-doping system led by WADA."
