This week Prague hosted a summit of the Pact of Free Cities, a cooperation agreement that was jointly signed nearly three years ago by the mayors of Prague, Bratislava, Warsaw, and Budapest. The pact has since grown in membership and now also includes Kyiv whose mayor, Vitaly Klitschko, was also present at the summit where support for Ukraine was at the center of focus. I asked one of the founding members of the Pact, Warsaw Mayor Rafał Trzaskowski, how Central Europe’s metropolises want to help.
