The appeasement policy is a policy of western countries to safeguard their own interests and sacrifice the interests of other countries in exchange for compromise with their opponents.

The appeasement policy pursued by Britain and France before the full-scale outbreak of World War II condoned the aggression and expansion of German and Italian fascists, and also caused great losses to the two countries themselves. Britain and France pursued the policy of appeasement for the following reasons:

First of all, the strategy adopted by Britain and France to maintain their hegemonic position in the case of declining strength. Britain suffered heavy losses in the First World War, and its post-war economic recovery was very slow. In the 1920s and 1930s, successive British governments focused on solving economic problems, regarded rearmament as an obstacle to economic recovery, and tried to maintain its hegemonic position with foreign policies without strength. Because France is adjacent to Germany, after World War I, France once maintained its armament and pursued a tough policy towards Germany. However, its economy has been in recession. In the period of relative stability, its development was limited, and the economic crisis of11930 s lasted for a long time. At the same time, the political situation in France is unstable, the cabinet changes frequently, and it is difficult to maintain firmness and continuity in foreign policy. In a word, the decline of Britain and France is the material basis of its appeasement policy.

Secondly, the implementation of appeasement policy is closely related to the background of the coexistence of two social systems at that time. After the October Revolution, the opposition and struggle between capitalism and socialist social system began in international relations. In order to prevent the influence of the Soviet Union, Britain, France and other western countries regard Germany as a barrier against Bolshevism. When Germany established a fascist regime and then tore up the Treaty of Versailles for external expansion, Britain and France tried their best to lead this disaster to the East.

Thirdly, the implementation of appeasement policy was also closely related to the prevailing social thoughts in the West at that time. The cruel scene of the First World War left a painful memory for European and American countries, so post-war pacifism and war-weariness were quite popular, especially in France. The rulers of Britain and France are not only influenced and restricted by pacifism, but also the promoters of this trend of thought. The appeasement policy is only the product of their implementation of this trend of thought.

With the connivance of the appeasement policy of Britain, France and the United States, Germany, Italy and Japan stepped up their foreign aggression and expansion, which made the contradictions between imperialist countries grow rapidly.

Huairou policy refers to using political means to win over other nationalities or countries and make them join their own policies. Corresponding to the means of war, the ethnic minorities in China were joined by means of conferring a king, conferring a knighthood, giving aid to others, and getting close to each other.
