Why did Franco-German reconciliation slow down after the 1926 meeting between Stresemann and Briand?

The Franco-German rapprochement stalled following the 1926 meeting between Gustav Stresemann and Aristide Briand primarily because the encounter generated exaggerated public expectations that could not be realized.1

While the meeting was intended to foster reconciliation, the resulting political atmosphere made it difficult to sustain progress. Stresemann’s tendency to make premature public statements often created hopes that were ultimately unattainable, leading to a standstill in the diplomatic process. Furthermore, in the final years of his life, Stresemann faced significant internal challenges; his own political party dwindled, and large segments of it shifted toward the extreme right, which severely hampered his ability to advance his foreign policy goals. These domestic struggles, combined with his declining health, contributed to the loss of momentum in the diplomatic efforts between the two nations.1
