Archaeological excavations indicate that Vietnam was inhabited as early as the Paleolithic age. The ancient Vietnamese nation was annexed by China in the 2nd century BC, which subsequently made Vietnam a division of China for over a millennium. The first independent monarchy emerged in the 10th century AD. This paved the way for successive imperial dynasties as the nation expanded geographically southward until the Indochinese Peninsula saw French colonisation in the mid-19th century. Modern Vietnam was born upon the Proclamation of Independence from France in 1945. Following Vietnamese victory against the French in the First Indochina War, which ended in 1954, the nation was divided into two rival states: communist North and anti-communist South. Conflicts intensified in the Vietnam War, which saw extensive US intervention in support of South Vietnam and ended with North Vietnamese victory in 1975. After North and South Vietnam were reunified under a unitarysocialist government in 1976, the country became economically and politically isolated until 1986, when the Communist Party initiated a series of economic and political reforms that facilitated Vietnamese integration into world politics and the global economy. As a result of the successful reforms, Vietnam has enjoyed a high GDP growth rate, consistently ranked among the fastest-growing countries in the world. It nevertheless faces challenges including poverty, corruption and inadequate social welfare. By 2010, Vietnam had established diplomatic relations with 178 countries.
As the country is located within the Indomalayan realm, Vietnam is one of twenty-five countries considered to possess a uniquely high level of biodiversity. This was noted in the country’s National Environmental Condition Report in 2005. It is ranked 16th worldwide in biological diversity, being home to approximately 16% of the world’s species. 15,986 species of flora have been identified in the country, of which 10% are endemic. Vietnam’s fauna includes: 307 nematode species, 200 oligochaeta, 145 acarina, 113 springtails, 7,750 insects, 260 reptiles, and 120 amphibians. 840 birds and 310 mammals are found in Vietnam, of which 100 birds and 78 mammals are endemic. Vietnam has two World Natural Heritage Sites, the Hạ Long Bay and Phong Nha-Kẻ Bàng National Park together with nine biosphere reserves including: Cần Giờ Mangrove Forest, Cát Tiên, Cát Bà, Kiên Giang, the Red River Delta, Mekong Delta, Western Nghệ An, Cà Mau and Cu Lao Cham Marine Park. Vietnam is also home to 1,438 species of freshwater microalgae, constituting 9.6% of all microalgae species, as well as 794 aquatic invertebrates and 2,458 species of sea fish. In recent years, 13 genera, 222 species, and 30 taxa of flora have been newly described in Vietnam. Six new mammal species, including the saola, giant muntjac and Tonkin snub-nosed monkey have also been discovered, along with one new bird species, the endangered Edwards’s pheasant. In the late 1980s, a small population of Javan rhinoceros was found in Cát Tiên National Park. However, the last individual of the species in Vietnam was reportedly shot in 2010. In agricultural genetic diversity, Vietnam is one of the world’s twelve original cultivar centres. The Vietnam National Cultivar Gene Bank preserves 12,300 cultivars of 115 species. The Vietnamese government spent US$49.07 million on the preservation of biodiversity in 2004 alone and has established 126 conservation areas, including 30 national parks.
Tourism is an important element of economic activity in the country, contributing 7.5% of the gross domestic product. Vietnam welcomed over 12.9 million visitors in 2017, an increase of 29.1% over the previous year, making it one of the fastest growing tourist destinations in recent years. The vast majority of visitors in 2017, 9.7 million, came from Asia. China (4 million), South Korea (2.6 million) and Japan (798,119) made up half of all international arrivals in 2017. Vietnam also attracts large numbers of visitors from Europe with almost 1.9 million visitors in 2017. Russia (574,164) and the United Kingdom (283,537), followed closely by France (255,396) and Germany (199,872) were the largest source of international arrivals from Europe. Other significant international arrivals by nationality include the United States (614,117) and Australia (370,438). The most visited destinations in Vietnam are Ho Chi Minh City with 5.8 million international arrivals, followed by Hanoi with 4.6 million and Hạ Long, including Hạ Long Bay with 4.4 million arrivals. All three are ranked in the top 100 most visited cities in the world. Vietnam is home to eight UNESCO World Heritage Sites in Southeast Asia. In 2018, Travel + Leisure ranked Hội An as one of the world’s top 15 best destinations to visit.
