Ukrainian President Petro Poroshenko has said in the aftermath of Britain's vote to leave the European Union that he "expects the sanctions against Russia as a country-aggressor" to be extended.
On June 24, Poroshenko linked European unity to the sanctions that Brussels has imposed against Russia for its role in Ukraine's crisis.
Poroshenko said, "Today, the current challenge for the European Union is to find a way to the hearts of Euroskeptics so as not to allow a single chance to the opponents of the Eurointegration project."
In 2014, despite pressure from Russia, Ukraine signed an Association Agreement with the EU as part of its bid to eventually join the bloc.
Meanwhile, Moldova's pro-EU Prime Minister Pavel Filip on June 24 called Britain's vote to leave the EU a "sad day for Europe."
Filip said Moldova remained committed to joining the EU, "despite the result in the U.K., because we trust the EU as a successful project."
Moldova also signed an Association Agreement with the EU in 2014.
