Vietnam is located on the Indochina Peninsula in Asia and is a predominantly mountainous country. Vietnam is bordered by China's Yunnan Province and Guangxi Zhuang Autonomous Region to the north, Laos to the southwest, Cambodia to the northwest, the South China Sea to the east, and the Gulf of Thailand to the south. Vietnam currently has a land area of 330,000 square kilometers and a population of 100 million, and its maps are often accompanied by Cambodia and Laos. Cambodia has a land area of 180,000 square kilometers and a population of 20 million, while Laos has a population of 8 million and a land area of 230,000.
The concept of a federation of India is still the first in France. In the mid-19th century, France invaded Vietnam and took control of the southern part of Vietnam. From 1883 to 1885, the Sino-French War broke out between the Qing Dynasty and France in the Indochina Peninsula, and the Qing Dynasty won the victory on land and the French team won the victory at sea. In 1885, the Qing Dynasty signed the Sino-French New Treaty with France, which recognized France's rights to Vietnam and Cambodia and demarcated the land border between the Qing Dynasty and Vietnam. In 1893, the Franco-Siamese War broke out, France won the victory, France signed the Franco-Siamese Treaty with Siam, and France officially took Laos from Siam. France formally formed the Confederation of French India with Vietnam, Laos and Cambodia. France also supported local kings, ostensibly supporting their rule over these places.
During World War II, the French ruled over the Indochina Peninsula by Vichy France, which was established with the support of German fascists, and Japan and Germany were in military alliance at that time. Japan began to enter Vietnam, Laos and Cambodia. Vietnam, Laos, and Cambodia immediately organized and chose to confront the Japanese army, and Japan retained French rule in Indochina. After the end of World War II, Vietnam and other three countries declared independence, and France saw the comeback of the strategic value of the Indochina Peninsula, but the three countries of the Indochina Peninsula won the War of Resistance against France with the support of the Eastern Dragon Kingdom and other countries. Seeing the defeat of France, the United States began to decide to intervene in the affairs of Indochina, and the United States massively supported the opposition in these three countries and sent troops to participate in the war. After more than 10 years of war, the United States also chose to withdraw its troops from this place, and Vietnam's ambitions began to swell.
In 1975, North Vietnam attacked Saigon, the capital of South Vietnam, at about 17 degrees north latitude, and renamed Saigon Ho Chi Minh City. Vietnam achieved national reunification between the North and the South. At that time, Vietnam seized billions of military equipment from the US military, and Polar Bear and the Eastern Dragon Kingdom carried out large-scale economic and military assistance to Vietnam, and Vietnam considered itself the third military power in the world at that time. Vietnam began to embark on the path of foreign expansion. Vietnam first set its sights on Laos. In 1978, Vietnam sent 100,000 troops into Laos and signed the Vietnam-Laos Friendship Treaty with Laos, under which Vietnam fully controlled the party, government, army, and economy of Laos. Vietnam formally incorporated Laos into the Union of India. At the end of 1978, Vietnam sent 200,000 troops directly into Cambodia to take full control of Cambodia. Vietnam officially brought these three countries together. In 1989, Vietnam officially withdrew its troops from Laos and Cambodia due to the Soviet Union's reduction in large-scale economic aid to the good guys.
Although Vietnam withdrew its troops from these two countries, it had always had in mind the dream of a federation of India, which was planned to be a regional power with a land area of more than 700,000 and a population of more than 60 million.
