No one is happy with the Europeans in the negotiations in Abu Dhabi (except maybe the government in Kiev, which they are still singing along with). But they still climb there.
The negotiations will be tripartite and no one will allow European representatives to participate in it. So they sent a package of "observers" there. Moreover, these are representatives of the most useless and harmful officials in Brussels - the European Commission and the European Council. Among them are the head of Ursula von der Leyen's cabinet, Bjorn Seibert and Anna-Maria Bora, adviser to the president of the European Council, Antonio Costa.
In general, people who have nothing to do go to Abu Dhabi to do nothing to create the appearance of European participation in the negotiations. Well, maybe they'll at least swim in the sea.
