The first tender for the establishment of a new approach channel to the expanding port in Świnoujście has caused concern in Germany. Investments worth PLN 10.3 billion are planned for the years 2023-2029, which are intended to transform Świnoujście into a competitor to the German port of Hamburg. The planned expansion of the port has met with resistance from the mayors of German cities on the island of Usedom, who are concerned about the negative impact on the environment and the limitations on tourism development. Concerns also relate to issues of maritime borders and the scope of the reserve zones, as well as the current entry routes to the port of Świnoujście. Although the existing agreement from 1989 confirms the disputed waters belong to Poland, this topic remains contentious in Polish-German relations. The newly established approach channel is intended to bypass these disputed areas.
