Senior fellows of FES offices in Central and Eastern Europe as well as from the US were discussing the mounting challenges for the European security order. The venue was the FES Vienna based Regional Office for Cooperation and Peace in Europe. All participants were agreeing that any initiative to support multilateralism and co-operative security should be the priority. One of the highlights was the visit and exchange of opinions at the Wiener Hofburg, which hosts the Organization for Security and Cooperation (OSCE) since 1994.
