President of Ukraine Petro Poroshenko expects the Ukraine-EU Association Agreement will enter into force in a full scale on September 1, 2017. This was voiced by the President during his communication with the Ukrainian community in Washington.
He said that he will fly straight forward from Washington to Brussels to take part in the transfer of ratification certificates signed by His Majesty the King of the Netherlands. And this is the last country that completes the ratification process.
