Town twinning relations, which were previously limited to mutual visits by mayors, are now a tool that enables municipalities and municipal staff to work in a project-oriented manner. Town twinning relations, which is one of the most effective branches of local diplomacy, are now built on concrete outputs. Therefore, we recommend the municipalities that want to establish town twinning relations to develop partnership projects for all other possible grant programs, especially the financial resources of the European Union. Following this we recommend that they carry out the project in a participatory and inclusive approach in order to establish a true town twinning relations with all stakeholders in city and to make sure that the public adopts the partnership relationship. The officialization of the town twinning relationship should be a project output at the end of the process.
