In November 2015, Russia was provisionally suspended from all international track and field athletic competitions by the International Association of Athletics Federations (IAAF) following a World Anti-Doping Agency (WADA) report into a doping program in the country.^[65] The IAAF announced that it would allow individual Russian athletes to apply for "exceptional eligibility" to participate in the Games as "neutral" athletes if it was independently verified that they had not engaged in doping nor in the Russian doping program.^[66]

On 24 July 2016, the IOC rejected the IAAF and WADA's recommendations to allow athletes to compete neutrally, stating that the Olympic Charter "does not foresee such 'neutral athletes'" and that it was each country's National Olympic Committee decision on which athletes would be competing.^[67] As a result, Russian athletes competed under the Russian flag, although they would compete under a neutral flag in the 2018 Winter Olympics following several developments concerning the doping investigation.
