Chinese declaration of war against Japan, 9 December 1941
Japan's national policy has always aimed at the domination of Asia and mastery of the Pacific. For more than four years China has resolutely resisted Japan's aggression, regardless of suffering and sacrifice, in order not only to maintain her national independence and freedom but also to uphold international law and justice and to promote world peace and human happiness.
China is a peace-loving nation. In taking up arms in self-defence, China entertained the hope that Japan might yet realise the futility of her plans of conquest. Throughout the struggle all the other powers have shown the utmost forbearance likewise in the hope that Japan might one day repent and mend her ways in the interest of peace in the entire Pacific region.
Unfortunately Japan's aggressive capacities prove to be incorrigible. After her long and fruitless attempt to conquer China, Japan, far from showing any signs of penitence, has treacherously launched an attack on China's friends, the United States and Great Britain, thus extending the theater of her aggressive activities and making herself the arch-enemy of justice and world peace.
This latest act of aggression on the part of Japan lays bare her insatiable ambitions and has created a situation that no nation which believes in international good faith and human decency can tolerate.
The Chinese Government hereby formally declares war on Japan. The Chinese Government further declares that all treaties, conventions, agreements and contracts regarding relations between China and Japan are and remain null and void.
