The political provisions of the treaty were signed on 21 March 2014, after a series of events that blocked their ratification led to a revolution in Ukraine and the fall of Viktor Yanukovych, then President-in-Office of Ukraine.  This fall was caused by Yanukovych`s last-minute refusal to sign the agreement. Instead, Russia, Ukraine`s second-largest trading partner, presented a link to the existing customs union of Russia, Belarus and Kazakhstan as an alternative.   After March 21, 2014, trade integration issues were temporarily suspended (pending the outcome of the Ukrainian presidential elections on 25 May 2014) until the European Union and new Ukrainian President Petro Poroshenko on 27 June 2014 signed the economic component of the Association Agreement between Ukraine and the European Union, which is the "first step" Ukraine`s move towards EU membership.  The implementation of the Association Agreement poses challenges for Ukraine. The DCFTA will cause some economic disruption in the near future, as it also expands the access of EU exporters to the Ukrainian market. But competition will help Ukrainian companies become more efficient. Most economists predict that the agreement will have a significant positive impact on Ukraine`s gross domestic product. The issue was a trade agreement and a political association agreement in 2005, when the EU launched its "Eastern Neighbourhood Policy", which offers trade and political advantages to post-Soviet states, traditionally in orbit in Moscow. Neighbourhood policy does not offer possible EU membership or accession negotiations. The Republic of Moldova and Georgia are expected to sign agreements with the EU.
The Association Agreement between Ukraine and the European Union is an association agreement between the European Union (EU), Euratom, Ukraine and the 28 UNION Member States (separate parts of the EU and Euratom). It creates a political and economic association between the parties. The agreement came into force on September 1, 2017 and some parts had previously been provisionally implemented. The parties pledged to cooperate in a wide range of areas and to end economic policy, legislation and regulation, including equal rights for workers, approaches to the free movement of persons, the exchange of information and staff in the field of justice, the modernisation of Ukraine`s energy infrastructure and access to the European Investment Bank. The parties committed to holding summit meetings and regular meetings between ministers, other officials and experts. In addition, the agreement establishes a comprehensive and comprehensive free trade area between the parties.
