Geography and climate
Vietnam is approximately 331,688 km? (128,066 sq mi) in area (not including Hoang Sa and Truong Sa islands), larger than Italy and almost the size of Germany. The perimeter of the country running along its international boundaries is 4,639 km (2,883 mi). The topography consists of hills and densely forested mountains, with level land covering no more than 20%. Mountains account for 40% of the area, with smaller hills accounting for 40% and tropical forests 42%. The northern part of the country consists mostly of highlands and the Red River Delta. Phan Xi P?ng, located in L?o Cai province, is the highest mountain in Vietnam at 3,143 m (10,312 ft). The south is divided into coastal lowlands, Annamite Chain peaks, extensive forests, and poor soil. Comprising five relatively flat plateaus of basalt soil, the highlands account for 16% of the country's arable land and 22% of its total forested land.

The delta of the Red River (also known as the S?ng H?ng), a flat, triangular region of 15,000 square kilometers, is smaller but more intensely developed and more densely populated than the Mekong River Delta. Once an inlet of the Gulf of Tonkin, it has been filled in by the enormous alluvial deposits of the rivers over a period of millennia, and it advances one hundred meters into the Gulf annually. The Mekong delta, covering about 40,000 square kilometers, is a low-level plain not more than three meters above sea level at any point and criss-crossed by a maze of canals and rivers. So much sediment is carried by the Mekong's various branches and tributaries that the delta advances sixty to eighty meters into the sea every year.

Because of differences in latitude and the marked variety of topographical relief, the climate tends to vary considerably from place to place. During the winter or dry season, extending roughly from November to April, the monsoon winds usually blow from the northeast along the China coast and across the Gulf of Tonkin, picking up considerable moisture; consequently the winter season in most parts of the country is dry only by comparison with the rainy or summer season. The average annual temperature is generally higher in the plains than in the mountains and plateaus and in the south than in the north. Temperatures in the southern plains (Ho Chi Minh City and the Mekong Delta) varies less, going between 21 and 28 degree Celsius (70 and 82.5 ?F) over the course of a year. The seasons in the mountains and plateaus and in the north are much more dramatic, and temperatures may vary from 5 degree Celsius (41 ?F) in December and January to 37 degree Celsius (98.6 ?F) in July and August.

Government and politics
The Socialist Republic of Vietnam is a single-party state. A new state constitution was approved in April 1992, replacing the 1975 version. The central role of the Communist Party was reasserted in all organs of government, politics and society. Only political organizations affiliated with or endorsed by the Communist Party are permitted to contest elections. These include the Vietnamese Fatherland Front, worker and trade unionist parties. Although the state remains officially committed to socialism as its defining creed, the ideology's importance has substantially diminished since the 1990s. The President of Vietnam is the titular head of state and the nominal commander in chief of the military of Vietnam, chairing the Council on National Defense and Security. The Prime Minister of Vietnam Nguyen Tan Dung is the head of government, presiding over a council of ministers composed of 3 deputy prime ministers and the heads of 26 ministries and commissions.

The National Assembly of Vietnam is the unicameral legislature of the government, composed of 498 members. It is superior to both the executive and judicial branches. All members of the council of ministers are derived from the National Assembly. The Supreme People's Court of Vietnam, which is the highest court of appeal in the nation, is also answerable to the National Assembly. Beneath the Supreme People's Court stand the provincial municipal courts and the local courts. Military courts are also a powerful branch of the judiciary with special jurisdiction in matters of national security. All organs of Vietnam's government are controlled by the Communist Party. Most government appointees are members of the party. The General Secretary of the Communist Party is perhaps one of the most important political leaders in the nation, controlling the party's national organization and state appointments, as well as setting policy.

The Vietnam People's Army is the official name for the combined military services of Vietnam, which is organized along the lines of China's People's Liberation Army. The VPA is further subdivided into the Vietnamese People's Ground Forces (including Strategic Rear Forces and Border Defense Forces), the Vietnam People's Navy, the Vietnam People's Air Force and the coast guard. Through Vietnam's recent history, the VPA has actively been involved in Vietnam's workforce to develop the economy of Vietnam, in order to coordinate national defense and the economy. The VPA is involved in such areas as industry, agriculture, forestry, fishery and telecommunications. The total strength of the VPA is close to 500,000 officers and enlisted members. The government also organizes and maintains provincial militias and police forces. The role of the military in public life has steadily been reduced since the 1980s.

Nature
Vietnam has two World's Natural Heritage sites: Halong Bay and Phong Nha-Ke Bang National Park and 6 World's biosphere reserves including: Can Gio Mangrove Forest, Cat Tien, Cat Ba, Kien Giang, Red River Delta, Western Nghe An.

Economy
The Vietnam War destroyed much of the economy of Vietnam. Upon taking power, the Government created a planned economy for the nation. Collectivization of farms, factories and economic capital was implemented, and millions of people were put to work in government programs. For many decades, Vietnam's economy was plagued with inefficiency and corruption in state programs, poor quality and underproduction and restrictions on economic activities and trade. It also suffered from the trade embargo from the United States and most of Europe after the Vietnam War. Subsequently, the trade partners of the Communist blocs began to erode. In 1986, the Sixth Party Congress introduced significant economic reforms with market economy elements as part of a broad economic reform package called "??i m?i" (Renovation). Private ownership was encouraged in industries, commerce and agriculture. Vietnam achieved around 8% annual GDP growth from 1990 to 1997 and continued at around 7% from 2000 to 2005, making it the world's second-fastest growing economy. Simultaneously, foreign investment grew threefold and domestic savings quintupled.

Manufacturing, information technology and high-tech industries form a large and fast-growing part of the national economy. Vietnam is a relative new-comer to the oil business, but today it is the third-largest oil producer in Southeast Asia with output of 400,000 barrels per day. Vietnam is one of Asia's most open economies: two-way trade is around 160% of GDP, more than twice the ratio for China and over four times India's.

Vietnam is still a relatively poor country with an annual GDP of US$280.2 billion at purchasing power parity (2006 estimate). This translates to a purchasing power of about US$3,300 per capita (or US$726 per capita at the market exchange rate). Inflation rate was estimated at 7.5% per year in 2006. Deep poverty, defined as a percent of the population living under $1 per day, has declined significantly and is now smaller than that of China, India, and the Philippines.

As a result of several land reform measures, Vietnam is now the largest producer of cashew nuts with a one-third global share and second largest rice exporter in the world after Thailand. Vietnam has the highest percent of land use for permanent crops, 6.93%, of any nation in the Greater Mekong Subregion. Besides rice, key exports are coffee, tea, rubber, and fishery products. However, agriculture's share of economic output has declined, falling as a share of GDP from 42% in 1989 to 20% in 2006, as production in other sectors of the economy has risen. According to the CIA World Fact Book, the unemployment rate in Vietnam is one of the lowest in the world at 2%, trailing behind only Azerbaijan, Cuba, Iceland, Andorra and Liechtenstein. Among other steps taken in the process of transitioning to a market economy, Vietnam in July 2006 updated its intellectual property legislation to comply with TRIPS. Vietnam was accepted into the WTO on November 7, 2006. Vietnam's chief trading partners include Japan, Australia, ASEAN countries, the U.S. and Western European countries.

Demography
Recent census estimates the population of Vietnam at beyond 84 million. Vietnamese people, also called "Viet" or "Kinh", account for 86.2 percent of the population. Their population is concentrated in the alluvial deltas and coastal plains of the country. A homogeneous social and ethnic majority group, the Kinh exert political and economic control. There are more than 54 ethnic minorities throughout the country, but the Kinh are purveyors of the dominant culture. Most ethnic minorities, such as the Muong, a closely related ethnic of the Kinh, are found mostly in the highlands covering two-thirds of the territory. The Hoa (ethnic Chinese) and Khmer Krom are mainly lowlanders. The largest ethnic minority groups include the Hmong, Dao, Tay, Thai, and Nung.

The people of Vietnam speak Vietnamese as a native language. In its early history, Vietnamese writing used Chinese characters. In the 13th century, the Vietnamese developed their own set of characters called Ch? n?m. The celebrated epic ?o?n tr??ng t?n thanh (Truy?n Ki?u or The Tale of Kieu) by Nguy?n Du was written in Ch? n?m. During the French colonial period, Qu?c ng?, the romanized Vietnamese alphabet used for spoken Vietnamese, which was developed in 17th century by Jesuit Alexandre De Rhodes and several other Catholic missionaries, became popular and brought literacy to the masses.

Various other languages are spoken by several minority groups in Vietnam. The most common of these are T?y, M??ng, Khmer, Chinese, N?ng, and H'M?ng. The French language, a legacy of colonial rule, is still spoken by some older Vietnamese as a second language, but is losing its popularity. Vietnam is also a full member of the Francophonie. Russian — and to a much lesser extent German, Czech, or Polish — is sometimes known among those whose families had ties with the Soviet bloc. In recent years, English is becoming more popular as a second language. English study is obligatory in most schools. Chinese and Japanese have also become more popular.

Culture
The spoken and written language is Vietnamese.

The culture of Vietnam has been influenced by neighboring China. Due to Vietnam's long association with the south of China, one characteristic of Vietnamese culture is financial duty. Education and self-betterment are highly valued. Historically, passing the imperial Mandarin exams was the only means for Vietnamese people to socially advance themselves.

In the socialist era, the cultural life of Vietnam has been deeply influenced by government-controlled media and the cultural influences of socialist programs. For many decades, foreign cultural influences were shunned and emphasis placed on appreciating and sharing the culture of communist nations such as the Soviet Union, China, Cuba and others. Since the 1990s, Vietnam has seen a greater exposure to Southeast Asian, European and American culture and media.

One of the most popular Vietnamese traditional garments is the "?o D?i", worn often for special occasions such as weddings or festivals. White ?o d?i is the required uniform for girls in many high schools across Vietnam. ?o D?i was once worn by both genders but today it is worn mainly by females, except for certain important traditional culture-related occasions where some men do wear it.

Vietnamese cuisine uses very little oil and many vegetables. The main dishes are often based on rice, soy sauce, and fish sauce. Its characteristic flavors are sweet (sugar), spicy (serrano peppers), sour (lime), nuoc mam (fish sauce), and flavored by a variety of mint and basil.

Vietnamese music varies slightly in the three regions: B?c or North, Trung or Central, and Nam or South. Northern classical music is Vietnam's oldest and is traditionally more formal. Vietnamese classical music can be traced to the Mongol invasions, when the Vietnamese captured a Chinese opera troupe. Central classical music shows the influences of Champa culture with its melancholic melodies. Southern music exudes a lively laissez-faire attitude.

Tourism
Vietnam's number of visitors for tourism and vacation has increased steadily over the past ten years. About 3.56 million international guests visited Vietnam in 2006, an increase of 3.7% from 2005. The country is investing capital into the coastal regions that are already popular for their beaches and boat tours. Hotel staff and tourism guides in these regions speak a good amount of English.
