Abstract: The article is devoted to the activity of the Yemen Republic's international and regional organizations. The author of the article analyze peucliarities of the union of two Yemen states, Yemen Arab Republic and People's Democratic Republic of Yemen as well as their influence on the foreign policy and diplomacy of the Yemen Republic in general. The researcher also touches upon peculiarities of creation of the Cooperation Council for the Arab States, participation of the Yemen Republic in the League of Arab States and Organization of Islamic Cooperation, and attempts to join the Gulf Cooperation Council. The researcher has applied general research methods such as analysis, observation, comparison, and methods of historical research such as historical description and historical comparison. The novelty of the research is caused by the fact that both Russian and foreign academic literature does not pay enough attention to the foreign policy of the Yemen Republic. Noteworthy that the study of the Middle East's countries such as Yemen, Syria, Iraq, Livia, Lebanon, etc. is difficult due to their chronic internal instability which includes but not limited to the influence of external factors at the regional and global levels. The main conclusion of the research is that despite the rich and long history, Yemen has not taken a decent place on the world arena yet, thus the country has been unable to make a name among influential international organizations. Its activity is limited to regional integrations only.
