Japanese Emperor and Government as well as the representative of the Japanese general headquarters signed the instrument of surrender. This crowned China's War of Resistance Against Japan and the Second World War with final victory. The War of Resistance Against Japan was a national liberation war in which the Chinese people won complete victory for the first time in a century-long struggle against foreign invaders and it was an important component of the anti-fascist world war.

Victory in the war of resistance was won through arduous and complicated struggle of the people of all nationalities throughout the country and at immense cost. According to statistics, over 21 million Chinese armymen and people were killed or wounded and the loss of property amounted to 60 billion U.S. dollars at least. During the eight years of the war of resistance, the Eighth Route Army, the New Fourth Army and other people's anti-Japanese armed forces led by the CPC fought 125,000 battles, wiping out 1,714,000 Japanese and puppet troops, capturing 694,000 arms of different kinds and 1,800 pieces of artillery. More than 600,000 commanders and fighters of the Communist-led armies lost their lives or got wounded and over 6 million people in the liberated areas were killed or wounded. Through the eight years of fighting, the people's revolutionary forces led by the CPC grew much stronger than before, the liberated areas covered an area of nearly one million square kilometres with a population of 100 million, and the main forces of the people's armies exceeded 1.2 million and the militia, 2.6 million. This laid a solid foundation for nationwide victory in the new-democratic revolution.
