The news follows reported threats by Slovakia and Hungary that they may block the extension unless six Russian businessmen are removed from the list.

When asked about the Ukraine-Russia talks, Kremlin spokesperson Dmitry Peskov replied that communication channels have been established and exist, but as of now, "it’s more accurate to say there is a pause" in dialogue.
