Abstrakt:
Cities are taking part in enforcing international standards/law by humanitarian assistance to Ukraine and relief for Ukrainian refugees, severing sister cities’ ties with Russian cities and breaking other forms of cooperation with them. This enforcement consists of implementing sanctions against Russia and supporting the victim of illegal Russian aggression in the exercise of collective self-defense. The research goal of this article is to examine the reaction of 12 cities (Amsterdam, Barcelona, Berlin, Brussels, Geneva, London, Madrid, Munich, Paris, Stockholm, Strasbourg and the Hague, chosen as part of a broader research project that the authors are implementing) to Russian aggression against Ukraine and on that basis to catalogue or classify their actions as well as answer the question whether they are enforcing international standards only by following their states’ actions or by acting ahead of them. The cities had been chosen as part of a broader research project that the authors are implementing. The research methods include desk analysis and multiple case studies. The information has mostly been obtained from the websites of the respective city councils as well as via e-mails from the International Affairs offices/officers of examined cities.
