Through Aug. 30, Ukraine has closed its two road checkpoints for entry into Russia-controlled Crimea, purportedly to control coronavirus. Only Crimean residents with Ukrainian passports are allowed to enter Crimea. Ukrainians who live on the mainland can return home. Although Russia’s annexation of the peninsula in 2014 radically cut Ukrainian tourism to Crimea, several hundred thousand Ukrainians travel to Crimea every summer, largely to visit friends and family and to check on their properties. There are no flights, ferries or trains between Ukraine and Crimea.
