Russia is banning exports of crude oil, petroleum products and coal to Ukraine.

"A few days ago the Ukrainian Cabinet of Ministers took the latest unfriendly step with respect to our country and expanded the list of Russian goods which cannot be imported to Ukrainian territory. In these conditions we are forced to protect our interests and take response measures," Russian Prime Minister Dmitry Medvedev said at a meeting of the Russian cabinet.

Medvedev said he had signed a resolution "banning the export of Russian crude oil and petroleum products to Ukraine."

The document "determines a list of those goods that it will be possible to export to Ukraine only on the basis of separate decisions from June 1." "This category includes fuel and energy products, including coal as well as the oil and petroleum products," he said.
