Before the treaty was signed, about one third of Ukraine`s foreign trade was with the European Union (EU); another third was with Russia.  The Association Agreement between Ukraine and the European Union is an association agreement between the European Union (EU), Euratom, Ukraine and the 28 MEMBER states of the UNION (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. The free trade agreement has comprehensive coverage, including trade in products (industrial and processed agricultural products, fish and other seafood), trade in services, investment, protection of intellectual property rights, public procurement and competition rules. Bilateral agreements on agricultural products between the various EFTA states and Ukraine are also part of the instruments for setting up the free trade area between the two sides. On 29 July 2013, Russia banned the import of chocolate products from the Ukrainian company Roshen and asked Belarus and Kazakhstan to follow suit.
A Russian health official said the company had failed to meet quality and safety standards, but critics said the ban was seen as a warning against closer cooperation between Ukraine and the EU. At the time, Roshen`s owner (and the future president of Ukraine), Petro Poroshenko, was considered pro-European.  On 14 August 2013, Russian Federal Customs officials began to carry out stricter inspections of shipments arriving from Ukraine than they would normally be.  This lasted until 20 August 27, 2013, and was followed by statements by the Chief Economic Adviser of the Russian President, Sergei Glazyev, who argued that the effects of the Russian response to Ukraine`s signing of the agreement, including tariffs and trade controls, could lead to a default of payment , a decline in living standards and “political and social unrest” in Ukraine and would be contrary to the Russian-Ukrainian Treaty of Strategy and Friendship.
