Despite strong opposition from Russia, the European Union has signed partnership agreements with Ukraine, Georgia and Moldova.
According to the BBC, the pact - which would bind the three countries more closely to the West both economically and politically - is at the heart of the crisis in Ukraine.
Following the signing of the pacts, Russian President Vladimir Putin said making Ukraine choose between Russia and the EU would split it in two.
Russia is reportedly concerned the deal could affect the Russian economy as the country's market would be flooded by cheap goods from the EU that is likely to hit Russian producers badly.
Meanwhile, as ceasefire with pro-Russian rebels in east Ukraine is due to end on Friday, Putin has called for a long-term ceasefire to allow talks between the government and separatists, the report added.
