Crimea one year after Russian annexation. EPC Policy Brief, 24 March 2015

On 18 March 2014, the Lower House of the Russian Parliament approved a Treaty to annex the Ukrainian Black Sea Peninsula of Crimea by 443 to 1 votes. This act violated Ukraine's sovereignty, representing a fundamental breach of international law; the Helsinki Final Act of 1975 and the terms of the 1994 Budapest Memorandum, whereby the nuclear arsenal stationed on Ukraine's territory after the collapse of the Soviet Union was relinquished in exchange for security assurances of its sovereign territorial integrity. Russia, the US, France and the UK all signed. The annexation also violated a number of bilateral agreements between Ukraine and Russia. Russia's actions were immediately condemned by the international community. A 13 March European Parliament Resolution "firmly condemns Russia's act of aggression in invading Crimea, which is an inseparable part of Ukraine and recognised as such by the Russian Federation".
