The research reports on the history of teaching Thai as a foreign language under a bachelor's degree program (Soviet-style master's degree) at universities throughout the Russian Federation. The purposes of the research article are to study the development of teaching Thai as a foreign language in Russian from the second half of the 20th century (when the teaching of Thai language began in the Soviet Union) to the present day and to find out which universities are currently teaching the Thai language in Russia (as of Academic Year 2020/21). Data were collected from the articles in scientific journals, bulletins, websites of the universities and institutes that offer degree programs with the study of the Thai language, an interview with Russian teachers, researchers, heads of the departments and faculties where the Thai language is taught. The results attained by this study are the following. Thai as a foreign language began to be taught in Moscow in 1954. There is a slight tendency towards an increase in interest in teaching and learning the Thai language in Russian Higher Educational Institutions. Although the number of universities teaching the Thai language is unstable, after 2014 the interest of students wishing to study Thai as a foreign language at universities was the highest compared to previous years and compared to other Southeast Asian languages. However, regardless of the increasing interest in learning the Thai language, it is not able to compete with the Chinese, Japanese, Korean and Arabic languages, which remain more attractive for university applicants. From 1999 until recently, only three cities had departments for Thai Studies – Moscow, St. Petersburg, and Vladivostok. They are considered to be centers for the Thai language. However, as of 2020, the Thai language is taught only in St. Petersburg (Faculty of Asian and African Studies of St. Petersburg University), and in Moscow (ISAA Moscow State University, MGIMO University, Institute for Oriental and Classical Studies of HSE University).
