If Ukraine would choose the agreement, the Eurasian Economic Commission's Customs Union of Belarus, Kazakhstan and Russia would withdraw from free trade agreements with the country, according to Russian presidential advisor Sergei Glazyev. However, on 21 November 2013 a Ukrainian government decree suspended preparations for signing the agreement that was scheduled to be signed during a 28–29 November 2013 EU summit in Vilnius, and it was not signed. The decision to put off signing the association agreement led to 2014 Ukrainian revolution.
