See here--it's two pages and is worth reading to see where the EU is right now.
The European Union strongly condemns the clear violation of Ukrainian sovereignty and territorial integrity by acts of aggression by the Russian armed forces as well as the authorisation given by the Federation Council of Russia on 1 March for the use of the armed forces on the territory of Ukraine. These actions are in clear breach of the UN Charter and the OSCE Helsinki Final Act, as well as of Russia's specific commitments to respect Ukraine's sovereignty and territorial integrity under the Budapest Memorandum of 1994 and the bilateral Treaty on Friendship, Cooperation and Partnership of 1997. These actions are also a clear breach of the Ukrainian constitution which specifically recognises the territorial integrity of the country and states that the Autonomous Republic of Crimea can only organise referenda on local matters but not on the modification of the territorial configuration of Ukraine.
The EU calls on Russia to immediately withdraw its armed forces to the are as of their permanent stationing, in accordance with the Agreement on the Status and Conditions of the Black Sea Fleet stationing on the territory of Ukraine of 1997. Russia should also without delay agree to the request by Ukraine to hold consultations, as foreseen in the bilateral Treaty on Friendship, Cooperation and Partnership of 1997, and to take part in urgent consultations among all signatories and adherents of the Budapest Memorandum of 1994.The document goes on to urge a peaceful resolution, praises Ukraine for its restraint so far and urges Russia to allow for the OSCE to conduct its factfinding mission. It also clarifies the purpose of the EU proposal that Yanukovich turned down:
The Council reconfirms its offer of the Association Agreement, including a Deep and Comprehensive Free Trade Area. The Agreement would bring opportunities for sustainable economic development and prosperity to all the regions of Ukraine, including Crimea, as well as to its neighbours. The Agreement does not constitute the final goal in EU-Ukraine cooperation. The EU reiterates its commitment to enhance people to people contacts between the EU and Ukraine, i.a. through the visa liberalisation process, in line with agreed conditions in the framework of the VLAP.Elsewhere, Russian PM Medvedev signed a decree authorizing the building of a bridge between Russia and the Crimea across the Kerch Strait at the eastern tip of the peninsula.
