Between January and September 2014, Russia banned imports of live pigs, fresh pork and other pig products from the entire EU, following an African swine flu outbreak in Latvia. The ban was declared as the Ukrainian crisis flared up between political forces aligned with Russia and those favouring closer relations with the EU. As war erupted between the two camps during the first half of 2014 and Russia annexed the Ukrainian region of Crimea, Moscow hardened economic sanctions against Western countries, resulting in the wider ban on European agricultural products in place for the past two years.
