If Ukraine opted for the agreement, the customs union of the Eurasian Economic Commission of Belarus, Kazakhstan and Russia would withdraw from free trade agreements with the country, said Russian presidential adviser Sergei Glazyev.  On 21 November 2013, a Ukrainian government decree suspended preparations for the signing of the agreement, which was to be signed at an EU summit in Vilnius from 28 to 29 November 2013, and it was not signed. [h]         The decision to organize the signing of the Association Agreement led to the Ukrainian revolution in 2014.   Kostiantyn Yelisieiev, Ukraine`s ambassador to the EU, reacted in February 2013 by rejecting all EU preconditions for the signing of the AA.  However, on 22 February 2013, 315 of the 349 registered members of the Verkhovna Rada adopted a resolution indicating that Parliament will ensure that the « recommendations » of the Foreign Affairs Council of 10 December 2012 are implemented « within its powers ».  At the 16th EU-Ukraine Summit on 25 February 2013, European Council President Herman Van Rompuy followed the Foreign Affairs Council`s December 2012 statement and reiterated the EU`s « demand for decisive action and tangible progress in these areas – no later than May of this year. »  On the same day, President Yanukovych declared that Ukraine would « do its best » to meet the EU`s requirements.  At the time, President Yanukovych was also in talks with Russia to find the « right model » of cooperation with the Customs Union of Belarus, Kazakhstan and Russia.  On 25 February 2013, European Commission President José Manuel Barroso also clarified that « a country cannot be both a member of a customs union and be in a deep free trade area with the European Union ».  Russian President Vladimir Putin has warned that members of the Customs Union of Belarus, Kazakhstan and Russia could impose safeguards in the event of trade liberalization between Ukraine and the EU.  [j] The EU condemned Russia`s threats and called them unacceptable.  Ukrainian Prime Minister Mykola Azarov urged Russia to « accept the reality that Ukraine signs the EU agreement » and condemned all artificial barriers as unnecessary.  The Association Agreement, in its scope and thematic coverage, is the largest international legal document in Ukraine`s history and the largest international agreement ever reached with a third country by the European Union.
On 11 July, the Council adopted, on behalf of the European Union, a decision on the conclusion of the Association Agreement with Ukraine. It will take place on the eve of the EU-Ukraine summit in Kiev on 12-13 July. After The 2014 Ukrainian revolution, President Viktor Yanukovych was removed from power by the majority of the Ukrainian parliament and replaced by a new transitional government in February 2014. At an EU summit on 21 March 22, 2014 in Brussels, the new Ukrainian Prime Minister, Arseniy Yatsenyuk, and the Heads of State and Government of the European Union, Herman Van Rompuy and José Manuel Barroso, have signed with the 28 political leaders or heads of state at the European Council in Brussels the political provisions of the AA with the DCFTA , which will be signed after the presidential elections in May 2014.   The European Union and the new Ukrainian President Petro Poroshenko signed the economic component of the Association Agreement between Ukraine and the European Union on 27 June 2014 and described Ukraine`s « decisive first step » towards EU membership.  European Council President Herman Van Rompuy said at the signing ceremony: « In Kiev and elsewhere, people have given their lives for these closer ties with the European Union.
