“So I would like to suggest during the working dinner of Heads of State and Government of the EU to start a special debate on this issue, I mean a strategy for Russia.

“I understand that a modern, stable and independent Ukraine is a kind of foundation for this new strategy. Therefore, this discussion will be very important not only for Ukraine but for the whole Europe.

"The EU leaders should send a strong signal of their readiness to support Ukraine both politically and financially.

"The situation is dramatic, it changes rapidly, and it requires immediate action.”
