The invasion was about border dispute between the Kampucheans and Vietnamese government. As Pol Pot wanted his nation to become "year zero" a utopia and agrarian society. As vision of following his theory of "year zero" he wanted the "lost" land which belongs to Khmer Empire long ago but the Vietnamese took it. As the Kampucheans negotiate with Vietnam about give their "land" back, the Vietnamese immediately rejected their claim. Pol Pot assign a invasion to Vietnam island, Phú Quốc. The Khmer Revolutionary army captured Phú Quốc, but the Vietnam People's Army quickly re-captured it again. Massacre was against the Vietnamese people who were living in Phú Quốc. As a return the VPA invaded Democratic Kampuchea with 120,000 troops and captured Phnom Penh in 17 days two years later from the Khmer Rouge invasion of Phú Quốc. They setup a pro-Vietnamese government in People's Republic of Kampuchea with a puppet. As a revenge, the Khmer Rouge seek for the Chinese for action, Eventually the Chinese attempt to invade Vietnam. PRC was defeated. There was 2 reason why they lost.
1. They did not reach to Hanoi
2. They did not get the Vietnamese out of Cambodia.
And there you have it -
Vietnam invaded Cambodia because Khmer Rouge massacre in Phú Quốc. (South of Cambodia)
Before the Japanese occupation of Vietnam during the Second World War, the country had been part of the French Empire. When the Japanese surrendered, France wanted Vietnam handed back to them. Many Vietnamese, however, did not wish to be under French control; they wanted independence! The Viet Minh ("The League for Vietnamese Independence) was formed, and Vietnamese independence was declared by its leader Ho Chi Minh. As a result of this declaration, France declared war on the Viet Minh and started to send troops to Vietnam.
The French colonization of Indochina (what is now Vietnam, Cambodia, and later Laos, possibly Siam [Thailand] 1887-1893 was part of the general European land grab by Britain, France, and the Netherlands of South Asia, Southeast Asia, the East Indies, Borneo, and New Guinea in the 19th century (also Africa, I might add) in order to gain empire and resources. The general pattern was to exploit the rich resources of rice, oil, iron ore, rubber, tin, and later bauxite and titanium, among others using colonials employed at slave wages. Basically they were seeking wealth and power, like every other industrialized nation. That's about all I know. Myself, I would like to know more of the details about which countries had which resources, how the various takeovers occured, how the various powers treated their colonies, and how any resulting rebellions fed into the Japanese takeover of that territory from December 1941 to May 1942. In many cases, the Japanese were welcomed with open arms under their promised theory of a "co-prosperity sphere," and "Asia for Asians." The countries thus overrun soon discovered that the devil they had known was better than the devil they didnt'. But I'm getting outside the topic. Jim Isham
Raw materials; which is a popular reason for war through out the ages, (oil, gold, silver, etc.). Vietnam is rich in rubber trees (natural rubber). There were other reasons; trade, distribution of world strategic competition between major world powers, and an excellent seaport, Cam Ranh Bay...so excellent in fact, that the Russian Battleship Fleet (which were big warships for that day) used that harbor for a rest & refit/resupply in 1905, enroute to their ill-fated battle at Tsushima (27 May 1905). The French being neutral in that particular war, had to ask the Russians to leave, or they (the French) would be in trouble with Great Britain and Japan...and no longer neutral.
France considered Vietnam,Cambodia, + Laos as colonies of the empire.
Ego and Natural Resources (especially with good sea ports). Nations with colonies were considered powerful countries.
