in general, France and Britain were aligned in their position on major issues. A key reason was the Francophile position of Foreign Minister Austen Chamberlain, and the ambassador to Paris the Marquess of Crewe (1922–28). They promoted a pro-French policy regarding French security and disarmament policy, the later stages of the Ruhr crisis, the implementation of the Geneva Protocol, the Treaty of Locarno and the origins of the Kellogg-Briand Pact. The high point of cooperation came with the Treaty of Locarno in 1925, which brought Germany into good terms with France and Britain. However, relations with France became increasingly tense because Chamberlain grew annoyed that foreign minister Aristide Briand's diplomatic agenda did not have at its heart a reinvigorated Entente Cordiale.
