223. Which country is a neighboring country of Germany?

Answer options

1. Romania
2. Bulgaria
3. Poland
4. Greece

Explanation

Poland is Germany’s eastern neighbor; their common frontier follows the Oder–Neisse line. Its legal recognition was consolidated by the Warsaw Treaty (1970), the Two Plus Four Treaty (1990), and the 1990 German-Polish Border Confirmation Treaty. The Basic Law reflects this postwar peace order through Article 25 (primacy of general rules of international law) and Article 23 (European integration), while Article 26 prohibits wars of aggression. Good-neighborly relations are now embedded legally and practically within the EU and the Schengen acquis.
