After the fall of Hong Kong, What happened to Macau, since it was part of neutral Portugal? Did the Japonese or the Allies respect Portugal neutrality?
Very good question, I searched it up and lo and behold this is what I found on Wikipedia
Macau became a refugee centre during World War II, causing its population to climb from about 200,000 to about 700,000 people within a few years.
Unlike in the case of [Portuguese Timor], which was occupied by the Japanese in 1942 along with Dutch Timor, the Japanese respected Portuguese neutrality in Macau, but only up to a point. As such, Macau enjoyed a brief period of economic prosperity, being the only neutral port in South China, after the Japanese had occupied Guangzhou (Canton) and Hong Kong. In August 1943, Japanese troops seized the British steamer Sian in Macau and killed about 20 guards. The next month, they demanded the installation of Japanese “advisors” under the alternative of military occupation. The result was that a virtual Japanese was created over Macau.
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 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 protest in 1950, the United States paid US$20,255,952 compensation to the government of Portugal
Long story short, Japanese respected neutrality Macau neutrality. When they found a British steamer they installed advisors (the portugese preferred this option rather than a full on invasion). So Macau was kinda puppeted.
