经济落后，工业孱弱，社会制度千疮百孔，军事上被动。如此贫弱的一个国家，要把抗战坚持到胜利，除了用自己的血肉作为屏障抵挡凶残的外敌，还需要外交求援。而外交，是要以国家的实力作为基础和后盾的。 当时的中国有这些实力吗？ 说话的腰杆子硬朗吗？ 有哪个国家真心实意地愿意帮助中国？ 抗战时期的中国外交就是在如此的内外交困中开展的。（For a weak country with undeveloped economy, vulnerable industry, numerous problems in social systems and inferior position in war, it needed to seek foreign aid through diplomacy in order to win the war besides combating against the ferocious enemies with the flesh. But diplomacy is based on national strength. Did China have these strengths at that time? Which country genuinely wanted to help China? Chinese diplomacy during the period of Anti Japanese war was carried out in a predicament both internally and externally.）
