   With 13,000 floral species and over 15,000 faunal species, three newly discovered big animal species, and a ratio of country/world species of 6.3%, Vietnam has enormous tourism - particularly ecotourism - potential. In fact, since 1986, when Renovation Reforms began the shift from a centrally planned to a socialist-oriented market, or multi-sectoral economy, tourism has been a sector of primary concern to the government. In May 1995, the prime minister of Vietnam approved a master plan of tourism development for the period 1995 - 2010. In February 1999, the state decree on tourism was part of the socio-economic development strategy for the period 2001 - 2010 approved at the IX National Congress of the Party: "Tourism development has become a spearhead economic industry indeed. It is necessary to improve the quality and effectiveness of tourism activities, bringing into full play the natural conditions, and cultural and historical tradition to meet the domestic and international demand for tourism and to catch up with tourism development in the region" (Document of the IX National Congress 2001).  

   Tourism has so far brought great benefits to the economy, but it has also contributed to environmental degradation, especially biodiversity deterioration. Thus, the concept of "sustainable development" - development which meets the needs of the present without compromising the ability of future generations to meet their own needs - must be factored into tourism development. This consideration is reflected in the term "ecotourism," which is referred to variously as ecological or environment tourism, nature or green tourism, sustainable or responsible tourism.

   Ecotourism involves travel to relatively undisturbed natural areas with the specific object of studying, admiring and enjoying scenery, plants and animals as well as any cultural features found in these areas. It is distinguished from mass or resort tourism by its lower impact on the environment, lower infrastructure requirements, and its role in educating tourists about natural environments and cultural values.

   Fully aware of its significance, the government of Vietnam has prioritized ecotourism in its strategy for tourism development to ensure both sustainability and economic benefits. Though ecotourism in Vietnam is at a beginning stage of development, it is expected to grow strongly through support from government and international organizations.
