"Demands about security guarantees and stopping the EU and NATO's eastward expansion are a purely Russian agenda with completely unacceptable conditions, especially regarding Ukraine", Borrell said in an interview with the German newspaper Die Welt, Sputnik reported.
On December 17, Russia published its projected agreements with the US and NATO member states on mutual security guarantees in Europe and non-deployment of intermediate- and short-range missiles within each other's reach.
The agreements also involve a demand for NATO to refrain from further expansion, including by accepting former Soviet republics.
According to Russian Deputy Foreign Minister Sergei Ryabkov, the NATO and US refusal to respond to Russia's demand for security guarantees could lead to a new phase of confrontation.
