一1937年“七七”事变后,南京国民政府立即展开全方位的试探性外交,以期探明与远东有着密切利害关系的主要欧美国家对中日战争的态度。但是,由于纳粹德国的崛起及欧洲局势的日趋严峻,英、法、苏等欧洲大国莫不忧心忡忡,它们不愿出面调解中日关系,以避免在远东再惹麻烦,而建议中国促请美国发起联合调解,它们则可以考虑参与联合行动。因此,从国民政府的角度来看,依靠外交手段缓和及解决中日问题的钥匙就落到了美国手中。 After the “July 7 Incident” of 1937, the Nanjing National Government immediately launched a full range of tentative diplomacy with a view to identifying the attitudes of the major European and American countries that have close interests with the Far East over the Sino-Japanese war. However, due to the rise of Nazi Germany and the increasingly serious situation in Europe, the major European powers such as Britain, France and the Soviet Union are not worried. They are not willing to mediate the Sino-Japanese relations so as to avoid any further trouble in the Far East. Instead, China is urged to urge the United States to initiate a joint mediation , They can consider participating in joint operations. Therefore, from the perspective of the Kuomintang government, the key to relying on diplomatic means to ease and solve the Sino-Japanese issue falls into the hands of the United States.
