In fact, we enforced a 5-year entry ban in order to ensure public security, including [for his] public support of military annexation of Crimea," she noted. Earlier, the first and last Soviet President Mikhail Gorbachev approved of the decision to annex Crimea and Sevastopol by Russia in March of 2014.
