Representatives of France, Germany and the United Kingdom, as well as the European Commission and NATO will participate in "separate segments of the negotiations in Abu Dhabi." The goal: "to disrupt Russia's attempts to use the US-led negotiations to change Europe's security architecture," reports the Financial Times, citing sources.
That is, no one invited them there, the negotiations remain triangular (Russia - USA - Ukraine), but the Europeans will try to "infiltrate" into "separate segments".
