Here's a short story:

Vietnam, officially the Socialist Republic of Vietnam, is the easternmost country on the Indochina Peninsula in Southeast Asia. With an estimated /1e6 round 1 million inhabitants , it is the world's 14th-most-populous country, and the ninth-most-populous Asian country. Vietnam is bordered by China to the north, Laos to the northwest, Cambodia to the southwest, Thailand across the Gulf of Thailand to the southwest, and the Philippines, Malaysia and Indonesia across the South China Sea to the east and southeast. Its capital city has been Hanoi since the reunification of North and South Vietnam in 1976, with Ho Chi Minh City as a historical city as well. 

The northern part of Vietnam was part of Imperial China for over a millennium, from 111 BC to AD 939. An independent Vietnamese state was formed in 939, following a Vietnamese victory in the Battle of Bạch Đằng River. Successive Vietnamese imperial dynasties flourished as the nation expanded geographically and politically into Southeast Asia, until the Indochina Peninsula was colonized by the French in the mid-19th century. 

Following a Japanese occupation in the 1940s, the Vietnamese fought French rule in the First Indochina War, eventually expelling the French in 1954. Thereafter, Vietnam was divided politically into two rival states, North Vietnam (officially the Democratic Republic of Vietnam), and South Vietnam (officially the Republic of Vietnam). Conflict between the two sides intensified in what is known as the Vietnam War, with heavy intervention by the United States on the side of South Vietnam from 1965 to 1973. The war ended with a North Vietnamese victory in 1975. (End of story)
