"I welcome the fact that the coalition agreement contains a clear commitment to concluding a supplementary agreement to the Berlin/Bonn Act and to strengthening Bonn as an international location. This will further secure Bonn's status as a second federal political center. I now expect that with this tailwind we will quickly conclude the supplementary agreement on the basis of the good results of the last legislative period. I am very pleased that, in addition to the supplementary agreement, Bonn as a UN city and seat of international organizations has also been explicitly mentioned in the coalition agreement. I am also grateful for the good cooperation across party lines, which has made this good result for Bonn possible."

Lines 802 and 803 of the coalition agreement state: "We stand by the Berlin/Bonn Act and will conclude a supplementary agreement." Lines 4006 and 4007 state that "The Federal Government will continue to develop the German UN headquarters in Bonn and will endeavor to attract additional UN institutions."
