The official website of the Olympic Games in Tokyo has published a map with the countries that take part in the Olympics. This information is available in the Schedule & Results section.
Among other countries, a map of Ukraine has been published, on which Crimea is separated from it by its border.
Thus, the IOC recognized the territorial affiliation of Crimea to Russia.
Crimea joined the Russian Federation following a referendum held in 2014. 96.77% of voters of the peninsula voted for it.
