• Japanese invasion
In conjunction with its military campaign, the Empire of Japan invaded Hong Kong on 8 December 1941. The Battle of Hong Kong ended with British and Canadian defenders surrendering control of the colony to Japan on 25 December. During the Japanese occupation of Hong Kong, civilians suffered widespread food shortages, rationing, and hyper-inflation due to forced exchange of currency for military notes. Through a policy of enforced repatriation of the unemployed to the mainland throughout the period, because of the scarcity of food, the population of Hong Kong had dwindled from 1.6 million in 1941 to 600,000 in 1945, when the United Kingdom resumed control of the colony.
• Cold war era
Hong Kong's population recovered quickly as a wave of migrants from China arrived for refuge from the ongoing Chinese Civil War. When the PRC was proclaimed in 1949, more migrants fled to Hong Kong for fear of persecution by the Communist Party. Many corporations in Shanghai and Guangzhou shifted their operations to Hong Kong.
