When it was discovered that neutral Macau was planning to sell aviation fuel to Japan, aircraft from the "USS Enterprise" bombed and strafed the hangar of the Naval Aviation Centre during the South China Sea raid on 16 January 1945 to destroy the fuel. American air raids on targets in Macau were also made on 25 February and 11 June 1945. Following Portuguese government protests, in 1950 the United States paid US$20,255,952 to Portugal. The Japanese presence ended in August 1945.
