==People==
Originating in what is now southern China and northern Vietnam, the Vietnamese people pushed southward over 2 millennia to occupy the entire eastern seacoast of the Indochinese Peninsula. Ethnic Vietnamese constitute about 90% of Vietnam's population.
Vietnam's approximately 2.3 million ethnic Chinese, concentrated mostly in southern Vietnam, constitute Vietnam's largest minority group. Long important in the Vietnamese economy, Vietnamese of Chinese ancestry have been active in rice trading, milling, real estate, and banking in the south and shop keeping, stevedoring, and mining in the north. Restrictions on economic activity following reunification of the north and south in 1975 and the subsequent but unrelated general deterioration in Vietnamese-Chinese relations sent chills through the Chinese-Vietnamese community. In 1978-79, some 450,000 ethnic Chinese left Vietnam by boat as refugees (many officially encouraged and assisted) or were expelled across the land border with China.
The second-largest ethnic minority grouping, the central highland peoples (formerly termed Montagnards or mountain people), comprise two main ethnolinguistic groups--Malayo-Polynesian and Mon-Khmer. About 30 groups of various cultures and dialects are spread over the highland territory.
The third-largest minority, the Khmer Krom (Cambodians), numbering about 600,000, is concentrated near the Cambodian border and at the mouth of the Mekong River. Most are farmers. Other minority groups include the Cham--remnants of the once-mighty Champa Kingdom, conquered by the Vietnamese in the 15th century--Hmong, and Thai.
Vietnamese is the official language of the country. It is a tonal language with influences from Thai, Khmer, and CantoneseChinese. Since the early 20th century, the Vietnamese have used a Romanized script introduced by the French. Previously, Chinese characters and an indigenous phonetic script were both used.

During the second Indochina war (1954-75), North Vietnam balanced relations with its two major allies, the Soviet Union and China. By 1975, tension began to grow as Beijing increasingly viewed Vietnam as a potential Soviet instrument to encircle China. Meanwhile, Beijing's increasing support for Cambodia's Khmer Rouge sparked Vietnamese suspicions of China's motives.
Vietnamese-Chinese relations deteriorated significantly after Hanoi instituted a ban in March 1978 on private trade, mostly affecting Sino-Vietnamese. Following Vietnam's December 1978 invasion of Cambodia, China launched a retaliatory incursion over Vietnam's northern border. Faced with severance of Chinese aid and strained international relations, Vietnam established even closer ties with the Soviet Union and its allies in the Council for Mutual Economic Assistance (Comecon). Through the 1980s, Vietnam received nearly $3 billion a year in economic and military aid from the Soviet Union and conducted most of its trade with that country and with other Council for Mutual Economic Assistance countries. However, Soviet and East bloc economic aid ceased after the breakup of the Soviet Union.
Vietnam did not begin to emerge from international isolation until it withdrew its troops from Cambodia in 1989. Within months of the 1991 Paris Agreements, Vietnam established diplomatic and economic relations with ASEAN as well as with most of the countries of Western Europe and Northeast Asia. China reestablished full diplomatic ties with Vietnam in 1991, and the two countries continue their joint efforts to demarcate their land and sea borders, expand trade and investment ties, and build political relations.
==History==
Vietnam's identity has been shaped by long-running conflicts, both internally and with foreign forces. In 111 BC, China's Han dynasty conquered northern Vietnam's Red River Delta and the ancestors of today's Vietnamese and Cantonese. Chinese dynasties ruled Vietnam for the next 1,000 years, inculcating it with Confucian ideas and political culture. In 939 AD, Vietnam achieved independence under a native dynasty. After 1471, when Vietnam conquered the Champa Kingdom in what is now central Vietnam, the Vietnamese moved gradually southward, finally reaching the rich Mekong Delta, encountering there earlier settled Cham and Cambodians. While Vietnam's emperors reigned ineffectually, powerful northern and southern families fought civil wars in the 17th and 18th centuries.
====French Rule and the Anti-Colonial Struggle====
Vietnam's invasion of Cambodia also heightened tensions that already existed between Vietnam and China. Beijing, which had long backed the Khmer Rouge regime in Cambodia, retaliated in early 1979 by initiating a border war with Vietnam.
Vietnam's tensions with its neighbors and its stagnant economy contributed to a massive exodus from Vietnam. Fearing persecution, many Chinese in particular fled Vietnam by boat to nearby countries. Later, hundreds of thousands of other Vietnamese nationals fledas well, seeking temporary refuge in camps throughout Southeast Asia.
The continuing grave condition of the economy and the alienation from the international community became focal points of party debate. In 1986, at the Sixth Party Congress, there was an important easing of communist agrarian and commercial policies.
