Berlin's CDU and SPD parties had already agreed in principle to twinning with Kyiv during their coalition negotiations. The parliamentary groups of both coalition partners then advanced the issue in the House of Representatives. In addition to Kyiv, Tel Aviv is also to become a new twin city. Klitschko had written to Wegner in May and asked the governing mayor about the possibility of a city partnership. According to the SPD, the twinning agreement is a gesture of solidarity with Ukraine. The country has been defending itself against the Russian invasion since February 2022.
