Which borders did Germany agree to respect in the Pact of Locarno?

In the Pact of Locarno (1925), Germany formally agreed to recognize the inviolability of its western frontiers with France and Belgium as established by the Treaty of Versailles.1

Under these agreements, Germany renounced the use of force to alter these western borders and committed to settling any future disputes with these nations through pacific means, such as arbitration.12

In contrast, Germany did not provide the same guarantee for its eastern frontiers. While it signed arbitration treaties regarding its borders with Poland and Czechoslovakia, it did not renounce the possibility of seeking future revisions to those boundaries through diplomatic or arbitral processes. This distinction was a central element of the foreign policy pursued by Gustav Stresemann, who sought to restore Germany's international standing while maintaining the flexibility to address eastern territorial issues.12
