Zelensky has been spearheading a drive to ban Russian and Belarusian athletes from participating in the games under a neutral flag. Zelensky has said their presence would normalise Russia’s invasion of his country and make “terror” acceptable.

“Ukraine has sent appropriate letters to the companies that provide the biggest support for the International Olympic Committee,” Zelensky said in his nightly video address.

“These are large international companies who clearly have an interest in ensuring that their reputation and support is not used for war propaganda.”

The IOC said in late January that the Olympic Council of Asia had offered Russian and Belarusian athletes the chance to compete in Asia, drawing an outcry from Kyiv which has called for Russian athletes to be banned over Russia’s invasion.

The committee said later it was standing by sanctions imposed against Russia, which invaded Ukraine nearly a year ago and Belarus whose authorities provided support for the invasion.
