"The EU-Ukraine-Russia talks (consultations on the free trade zone between Ukraine and EU - Ed.) were held yesterday. Russia's position is non-constructive. We will not surrender to intimidation... I am confident that the EU will demonstrate its unity (in the issue of the extension of sanctions - Ed.)," Poroshenko said.
He also expressed confidence that Ukraine had become stronger and more independent from the Russian Federation since Vilnius Summit 2013 (when ex-president Viktor Yanukovych refused to sign the agreement on Ukraine-EU integration - Ed.).
Poroshenko also condemned the sanctions imposed by Russia against Turkey after the incident with the downed Su-24.
"Russia imposes political sanctions both against Ukraine and Turkey. We will not let the Russian sanctions to determine the political future of Ukraine," he said.
"We will no longer allow intimidating us neither by the Russian duties nor the Russian sanctions," Poroshenko said.
Earlier, Foreign Minister of Ukraine Pavlo Klimkin stated that he considered trilateral Ukraine-EU-Russia consultations on the implementation of the trade part of the Ukraine-EU Association Agreement to be unsuccessful. Russia has offered Ukraine to impose "restrictive measures" against the EU.
