After the victory in World War II and Japan's surrender, if there is no civil war, the Chinese army will enjoy the results of the victory it deserves, and what areas may be gained:
The first is the Ryukyu Islands, the Japanese island of Shikoku. At the Cairo Conference, Roosevelt proposed that Ryukyu be handed over to the Kuomintang; the Japanese island of Shikoku was the area where Chinese troops were stationed after Japan's surrender.
The partition of Japan in World War II
The Indochina Peninsula (Vietnam, Cambodia and Laos), the French colony in the Far East, the Indochina Peninsula was handed over to Japan by France during World War II, Japan was defeated, and since France contributed almost nothing in the War of Resistance in the Far East, it was feasible to hand over the Indochina Peninsula to China for administration.
Myanmar. During World War II, when Japan occupied Burma and expelled the British army, China sent an expeditionary force into Burma to fight the Japanese army in order to protect the international transportation of supplies, and suffered more than 50,000 casualties.
Malaya, Singapore. The Eastern Theater of World War II was almost a war between the United States and Japan, britain contributed almost nothing, and the U.S.-Japan Pacific War did not affect here.
Indonesia. The Japanese army invaded indonesia, the original suzerainty was the Netherlands, and the Netherlands hardly fought with Japan.
Thailand has its own king, thailand was not colonized during the great colonial era, and maintained its independence during World War II, so Thailand was also an independent country after the war.
During the Pacific War, the United States was the main force to defeat Japan, so there would be American troops stationed in Guam, the Mariana Islands, Midway, Guadalcanal, and the Philippines.
Under the Yalta Agreement, the northern part of the Korean Peninsula was placed under the jurisdiction of the Soviet Union and the southern part of the Korean Peninsula was assigned to the United States.
Imperial Japan
Regarding the Lost Outer Mongolia, Outer Northeast, Outer Northwest Regions of Modern China: These areas will not return to China after World War II, first the Outer Northeast, the Outer Northwest directly merged into the territory of the Soviet Union, under the jurisdiction of the CpSU, and Outer Mongolia was a vassal state of the Soviet Union. Secondly, during the Period of the Great Patriotic War of the Soviet Union, a unified nationality and cultural consciousness had been formed, and the Outer Northwest and Outer Northeast had long recognized themselves as Soviets; in 1939, the Soviet-Mongolian coalition army and the Japanese-Manchurian coalition army clashed in Nomonkan, and in August 1945, the Soviet-Mongolian coalition army sent troops to the northeast, and these two battles strengthened the friendship between the two countries.
According to the above analysis, after the victory in World War II and the surrender of Japan, if there is no civil war, China may send troops to the Ryukyu Islands, the Japanese Shikoku Islands, the French colony in Asia - The Indochina Peninsula, the British colony in Southeast Asia - Burma, Malaya, Singapore, and the Dutch East Indies.
Among them, northern Vietnam is most likely to return to China after the victory in World War II. Here's why:
First of all, northern Vietnam was a territory directly under the central plains from the qin shi huang period to the Five Dynasties and Ten Kingdoms period. During the reign of Emperor Wu of the Han Dynasty, the three counties of Annam (Jiaotong County, Jiuzhen County, and Ninan County) were established in northern Vietnam; during the Tang Dynasty, the Annam Capital Protectorate was established, the great poet Wang Bo of the early Tang Dynasty drowned in Jiaotong, and the Tang Dynasty Prime Minister Jiang Gongfu was born in Vietnam; the Ming Dynasty ruled Annamda with a county system for 20 years.
It can be said that northern Vietnam is a territory directly under the Han nationality, not a vassal, not a feudal, but an area under the jurisdiction of the county system.
Secondly, after the victory of World War II, northern Vietnam was the area where Chinese troops received the surrender of the Japanese army, and after the victory of the Anti-Japanese War in 1945, Lu Han, a powerful figure in Yunnan, led his troops to Vietnam to be surrendered, which was the only unit in China to accept the surrender of the Japanese army.
At the final Cairo Conference, Roosevelt proposed that Vietnam be returned to China after the war, and Chiang Kai-shek had no time to take care of it because of the civil war. In most people's minds, Roosevelt handed over the Ryukyu Islands to Chiang Kai-shek's trusteeship, but in fact this is unreasonable, because the Ryukyu Islands were fought by the US military at the expense of 75,000 people, and it was also the most tragic battle during the US-Japan Pacific War. But Vietnam was different, France did not go to war with Japan in the Far East, vietnam did not have much war during the Japanese occupation period, and after Japan's surrender, the Allies agreed to take over northern Vietnam by China. Therefore, it is more realistic for Roosevelt to hand over northern Vietnam to China, and it is unrealistic to return Ryukyu.
Cairo Conference
To sum up, after the victory of the War of Resistance, if there is no civil war, China is most likely to get northern Vietnam.
