The Second Sino-Japanese War (1937–1945) was a military conflict that was primarily waged between the Republic of China and the Empire of Japan. The war made up the Chinese theater of the wider Pacific Theater of the Second World War. The beginning of the war is conventionally dated to the Marco Polo Bridge Incident on 7 July 1937, when a dispute between Japanese and Chinese troops in Peking escalated into a full-scale invasion. This full-scale war between the Chinese and the Empire of Japan is often regarded as the beginning of World War II in Asia. In 2017 the Ministry of Education in the People's Republic of China decreed that the term "eight-year war" in all textbooks should be replaced by "fourteen-year war", with a revised starting date of 18 September 1931 provided by the Japanese invasion of Manchuria. According to historian Rana Mitter, historians in China are unhappy with the blanket revision, and the Republic of China did not consider itself to be continuously at war with Japan over these six years. The Tanggu Truce of 1933 officially ended the earlier hostilities in Manchuria while the He-Umezu Agreement of 1935 acknowledged the Japanese demands to put an end to all anti-Japanese organizations in China.

The 2015 China Victory Day parade was a military parade held along Changan Avenue, Beijing, on 3 September 2015 to celebrate the 70th anniversary of Victory over Japan Day of World War II.

The Burma Road was a road linking Burma with southwest China. Its terminals were Kunming, Yunnan, and Lashio, Burma. It was built while Burma was a British colony to convey supplies to China during the Second Sino-Japanese War.

Use of the road was restored to the Allies in 1945 after the completion of the Ledo Road. Some parts of the old road are still visible today.

The Canton Operation was part of a campaign by Japan during the Second Sino-Japanese War to blockade China to prevent it from communicating with the outside world and importing needed arms and materials.

The Changsha fire of 1938, also known as Wenxi fire, was the greatest human-caused citywide fire in Chinese history. Kuomintang officials ordered the city be set on fire in 1938 during the Second Sino-Japanese War to prevent the Japanese from benefiting from its capture. The result of this fire made Changsha one of the most damaged cities during World War II, alongside Stalingrad, Hiroshima, Nagasaki, Tokyo, Dresden and others.

The Central Soviet was the main base of the Communist Party where Communist Party leader Mao Zedong issued a directive on 1 September 1931 for the Central Soviet to mass mobilize the region as a base area. As problems occurred over being able to control territories outside the Central Soviet, by 1933 a full transfer of Communist forces to the Central Soviet was achieved.

The Republic of China Air Force (ROCAF) was officially formed by the Kuomintang (KMT) after the establishment of the Aviation Ministry in 1920. As tensions mounted between China and Imperial Japan in the 1930s, air units from the Chinese warlords, including those from the Guangdong Provincial Air Force, and overseas Chinese aviators, became integrated into the centralized command of the ROCAF, nominally as the Nationalist Air Force of China, and coordinating with the Second United Front to counter the Imperial Japanese invasion and occupation.

In the United States, it helped solidify the popular view that Japan was morally wrong in their war against China, but the incident was not enough to spur the US into action against Japan despite Chinese entreaties. The Kweilin was re-built, and destroyed by the Japanese a second time two years later.

The Japanese claimed that they did not see the U.S. flags painted on the deck of the gunboat. Tokyo officially apologized, and paid a cash indemnity. The settlement mollified some of the U.S. anger, and newspapers called the matter closed.

The Provisional Government of the Republic of China was a Chinese puppet state of the Empire of Japan that existed from 1937 to 1940 during the Second Sino-Japanese War. It had been formed largely on the initiative of Imperial Japanese Army commanders in north China, before securing approval from Japanese government authorities in Tokyo. Thus the Provisional Government had nominal authority in Japanese occupied zones in north China, while to the south the Central China Expeditionary Army established the Reformed Government of the Republic of China in 1938, which had authority in the Yangtze River area. Both essentially served as a local organ of the Japanese military authorities, due to the presence and extensive powers of Japanese advisors within the Provisional Government over native Chinese bureaucrats, and because it never made any attempt to secure international recognition, even from Japan.

The Reformed Government of the Republic of China was a Chinese puppet state created by Japan that existed from 1938 to 1940 during the Second Sino-Japanese War. The regime had little authority or popular support, nor did it receive international recognition even from Japan itself, lasting only two years before it was merged with the Provisional Government into the Reorganized National Government of the Republic of China under Wang Jingwei. Due to the extensive powers of the Japanese advisors within the government and its own limited powers, the Reformed Government was not much more than an arm of the Japanese military administration.

The Second United Front was the alliance between the Chinese Nationalist Party and the Chinese Communist Party (CCP) to resist the Japanese invasion during the Second Sino-Japanese War, which suspended the Chinese Civil War from 1937 to 1941.

The Wang Jingwei regime is the common name of the Reorganized National Government of the Republic of China, the government of the puppet state of the Empire of Japan in eastern China called simply the Republic of China. This should not be confused with the contemporaneously existing National Government of the Republic of China under Chiang Kai-shek, which was fighting with the Allies of World War II against Japan during this period. The country was ruled as a one-party republic under Wang Jingwei, a very high-ranking former Kuomintang (KMT) official. The region that it would administer was initially seized by Japan throughout the late 1930s with the beginning of the Second Sino-Japanese War. Wang, a rival of Chiang Kai-shek and member of the pro-peace faction of the KMT, defected to the Japanese side and formed a collaborationist government in occupied Nanking (Nanjing) in 1940. The new state claimed the entirety of China during its existence, portraying itself as the legitimate inheritors of the Xinhai Revolution and Sun Yat-sen's legacy as opposed to Chiang Kai-shek's government in Chunking (Chongqing), but effectively only Japanese-occupied territory was under its direct control. Its international recognition was limited to other members of the Anti-Comintern Pact, of which it was a signatory. The Reorganized National Government existed until the end of World War II and the surrender of Japan in August 1945, at which point the regime was dissolved and many of its leading members were executed for treason.

X Force was the name given to the portion of the National Revolutionary Army's Chinese Expeditionary Force that retreated from Burma into India in 1942. Chiang Kai-shek sent troops into Burma from Yunnan in 1942 to assist the British in holding back the Japanese. These Chinese forces became broken up, and in the retreat out of Burma part of these forces entered India. These were cantoned at Ramgarh Cantonment in the Bihar Province, brought up to five-Division strength, and re-equipped and re-trained by American instructors at British expense.
