"If Ukraine doesn't come through with the reforms linked to the Minsk peace process, it will be very difficult for Europe to continue united in support for sanctions against Russia," Kristian Jensen told Politiken.
“Ukraine has a deadline. They need to push those reforms now, they can't wait,” he added.
Earlier it was reported that the Ukrainian parliament was considering a motion to scrap visa-free travel with Russia.
Mr. Jensen’s warning was not lost of the head of the State Duma’s International Affairs Committee, Alexei Pushkov.
“The Danish Foreign Minister said what Berlin is afraid to say: if Kiev does not start implementing Minsk-2, the EU countries will lift their sanctions against Russia,” Pushkov wrote on his Twitter account on Saturday
The conflict has resulted in over 9,000 deaths and the displacement of more than 2 million people, according to the UN.
