Speaking March 7 in Warsaw, the American diplomat said: "It is important that the US, EU, Ukraine and other countries do not recognize the Russian annexation of the Crimea. I think it's time to think about how we can make our position more rigid, including the consequences for travel, trade and business contacts with this territory ".

According to Volker, the situation with the Crimea and the Donbas are identical. The only difference is that there are no regular military operations on the peninsula involving Ukrainian troops.

During his visit to Warsaw, Volker met with the Polish foreign minister and the president's chancellery. At the meetings, the issue of regional security and ways to resolve the conflict in the Donbass was discussed, Ukrinform reports..
