Russian EU envoy Vladimir Chizhov has warned that Ukraine’s planned signing of a free trade deal with the European Union will carry “consequences,” including higher tariffs.

Chizhov made the comments on Wednesday, just two days before Kiev is due to sign an Association Agreement with the EU.

The Russian envoy added that the association agreement would violate Kiev’s existing trade agreements with Moscow.

In addition, Chizhov said "other retaliatory measures in case of adverse influence will undoubtedly be considered," including taking Kiev to the World Trade Organization (WTO) to settle disputes.

A similar warning was also made by Sergey Glazyev, an economic aide to Russian President Vladimir Putin.

“For Ukraine, signing the agreement is economic suicide,” said Sergey Glazyev, warning of a sharp currency devaluation, soaring inflation, and lower living standards.

Ukraine’s western-backed President Petro Poroshenko is set to sign the economic section of the agreement on June 27.

Under the deal, Brussels demands Ukraine open its doors to EU’s free trade zone and lift import barriers.

The Association Agreement between the 28-member bloc and Ukraine is the one now-ousted Ukrainian president Viktor Yanukovych refused to sign.
