In 1922–23 Curzon had to negotiate with France after French troops occupied the Ruhr to enforce the payment of German reparations; he described the French Prime Minister (and former President) Raymond Poincaré as a "horrid little man". Curzon had expansive ambitions and was not much happier with Bonar Law, whose foreign policy was based on "retrenchment and withdrawal", than he had been with Lloyd George. However he provided invaluable insight into the Middle East and was instrumental in shaping British foreign policy in that region.
