And here is Ukrainian President Petro Poroshenko speaking today from Riga:
"We don't see any alternative to the Minsk process. We, as one of the leaders of the European Union said, that Ukraine would be whiter than white to keep all the criteria, all the things to implement in the Minsk process and now we have the full evidence of the presence of the Russian Army [in Ukraine], the regular troops. Today, as you probably know, the OSCE and the International [Committee of the] Red Cross made an official statement about the soldiers who are now in our hospital receiving proper treatment as real soldiers of the Russian troops."
"The key element for us is to keep the European door open and we are ready to reform the country, to demonstrate a real fight against corruption, to improve the investment climate in Ukraine."
"The vital signal for us, we need to demonstrate two things: the unity of the European Union and the solidarity with Ukraine."
European Council President Donald Tusk speaking to reporters in Riga on the evening of May 21:
"Let me reply to those who claim that the Eastern Partnership is directed against Russia. It is not. The Eastern Partnership is not a beauty contest between Russia and the EU. But let me be frank. Beauty does count. If Russia was a bit softer, more charming, more attractive, perhaps it would not have to compensate its shortcomings by destructive, aggressive, and bullying tactics against its neighbors."
