The Schengen area initially had its legal basis outside the European Economic Community at the time, since it had been created by a subgroup of Community Member States with two international agreements: in 2002, the European Commissioner for Enlargement, Gonter Verheugen, said that a « European perspective » for Ukraine did not necessarily mean membership within 10 to 20 years; But it is a possibility. The same year, Ukrainian President Leonid Kuchma said that Ukraine intended to sign an association agreement with the EU by 2003-2004 and that ukraine would meet all EU membership requirements by 2007-2011.  As part of the Eastern Partnership, Poland and Ukraine have concluded a new agreement that replaces visas with simplified authorizations for Ukrainians within a 30 km radius of the border. Up to 1.5 million people can benefit from the agreement, which came into force on July 1, 2009.  In 1999, the United Kingdom formally requested participation in certain provisions of the Schengen acquis – Title III on police security and judicial cooperation – in 1999, and this request was approved by the Council of the European Union on 29 May 2000.  The UK`s formal participation in previously approved areas of cooperation was brought into effect by a 2004 Council decision that came into force on 1 January 2005.  Although the United Kingdom was not part of the Schengen area, it has always used the Schengen information system, a government database used by European countries to store and disseminate information on individuals and goods. This has allowed the UK to exchange information with countries that are part of the Schengen Agreement, often to connect to legal proceedings.  In 2020, the United Kingdom has declared that it will withdraw from these agreements at the end of its transition period. Viktor Yanukovych and his government were removed from office by Parliament after the 2014 Ukrainian revolution in February 2014.   Yanukovych`s fall plunged Ukraine into the 2014 crisis in Crimea and the pro-Russian conflict in Ukraine in 2014.
  In March 2014, the EU condemned Russia`s annexation of Crimea and the « clear violation of Ukraine`s sovereignty and territorial integrity by the aggression of the Russian armed forces ».
