Kunming, also known as Yunnan-Fu, is the capital and largest city of Yunnan province, China

Kunming was transformed into a modern city as a result of fighting of the Second Sino-Japanese War/World War II in 1937 with the outbreak of the Battles of ShanghaiNanking and Taiyuan, forcing a great movement of refugees from the north and eastern coastal regions of China,[21] bringing much commerce and industry into the southwest of China, including Kunming. They carried dismantled industrial plants with them, which were then re-erected beyond the range of Japanese bombers. In addition, a number of universities and institutes of higher education were evacuated there. The increased trade and expertise quickly established Kunming as an industrial and manufacturing base for the wartime government in Chongqing.

As the battles of Shanghai, Taiyuan and Nanjing were lost by the end of 1937, and with Wuhan falling into Japanese occupation by the end of 1938, many more of China's military forces and civilians retreated to cities outside the reach of the Japanese military ground forces a year prior to the outbreak of the Second World War in Europe in 1939, including the relocation of the Chinese Air Force Academy from Jianqiao Airbase to Kunming's Wujiaba Airbase, where the airfield was vastly expanded, becoming the new training hub for the battered but regrouped Chinese Air Force in which Lieutenant General Claire Lee Chennault took command of cadet training duties in the summer of 1938. The Chinese Air Force command established the 41st Pursuit Squadron based in Kunming, also known as the French Volunteer Group squadron in June 1938, and with them they brought Dewoitine D.510 fighters, with the intention of securing the sale of the planes to the Chinese Air Force; the French participated in some combat engagements against Japanese raids, including dogfights against Mitsubishi A5M fighters with Chinese Hawk III fighters over Nanchang, but after several setbacks, including a fighter pilot KIA, the group was disbanded in October 1938.

Although the Empire of Japan was focusing on ending the Chinese war of resistance at the Battle of Chonqing and Chengdu, Kunming was not out of the reach of Japanese air raids, and faced attacks by IJAAF and IJNAF bombers; military assets and infrastructure were under regular attack, while the RoCAF 18th Fighter Squadron and units of the Air Force Academy at Wujiaba were tasked with aerial defense of Kunming. The city of Kunming was prepared as an alternate National Redoubt in case the temporary capital in Chongqing fell, with an elaborate system of caves to serve as offices, barracks and factories, but never utilised. Kunming was to have served again in this role during the ensuing Chinese Civil War, but the Nationalist garrison there switched sides and joined the Communists. Instead Taiwan would become the last redoubt and home of the Republic of China government; a role it fulfills to this day.

When the city of Nanning fell to the Japanese during the Battle of South Guangxi, China's sea-access was cut off. However, the Chinese victory at the Battle of Kunlun Pass kept the Burma Road open. When the Japanese began occupying French Indochina in 1940, the Burma Road that linked Kunming and the outside-world with unoccupied China grew increasingly vital as much of the essential support and materials were imported through Burma. After the attack on Pearl Harbor, and the start of the Pacific War in December 1941, Kunming acted as an Allied military command center, which grouped the Chinese, American, British and French forces together for operations in Southeast Asia. Kunming became the northern and easternmost terminus of the vital war-supply line into China known as "The Hump', which stretched over the Himalayas from British bases in India to port-of-entry Kunming. The Office of Strategic Services' Service Unit Detachment 101 (predecessor to the 1st Special Forces Group) was also headquartered in Kunming. Its mission was to divert and disrupt Japanese combat operations in Burma.

Kunming, the northern terminus of all three of the Burma Road, the Ledo Road, and The Hump supply-line, was increasingly targeted by the IJAAF. When the Burma Road was lost to the Japanese, the Hump became China's primary lifeline to the outside world. The 1st American Volunteer Group, known as the "Flying Tigers", was based in Kunming and tasked with defense of The Hump supply-line against Japanese aerial interceptions.

Industry became important in Kunming during World War II. The large state-owned Central Machine Works was transferred there from Hunan, while the manufacture of electrical products, copper, cement, steel, paper, and textiles expanded.
