The article gives a brief description of the migration from Vietnam to Russia. The place of migration from Vietnam in global migration turnover is represented, as well as historical forms of migration and the relationship between Vietnam and the Soviet Union on the one hand, and later Russia, on the other hand. As a result of climate change on the planet Vietnam faced with new challenges and threats. Geographical position peculiarity, relief and demographic potential of the territory led to the need of revision of the existing and well-established policy of resettlement of the population across the country. Speaking of global climate change on our planet, one implies the average temperature of the environment increase, including the temperature of the water of the World Ocean. This given phenomenon is also denoted as the term "global warming". Negative phenomena, frequent due to climate change, in the medium term outlook will require the development of a new concept of migration policy in Vietnam, mostly aimed at the resettlement of people from potentially dangerous places of residence, primarily coastal areas. When considering the stated problem, the authors show the gradation of concepts like "climate migrants", "environmental migrants", "environmental refugee". In implementing the most unfavorable forecasts, the country will face the need of resettlement of millions of people. In the conditions of the limited area of the country thousands of people will be looking for a new place of residence outside the country.
