Abstract: The article examines the activities of the Shanghai Cooperation Organization in the field of coordinating the activities of the member states in the fight against terrorism. The author considers the complex use of various international legal instruments tested in practice in the fight against terrorist crime. The theoretical basis of the study is the research of A.A. Sinyakina, E. Umarakhunova, E.A. Chernyadeva. To determine the main instruments in the fight against terrorism, were analyzed international legal documents adopted at the SCO summits, in particular the Shanghai Convention on Combating Terrorism. In addition, as an example, were considered the structure and operation of the Regional Anti-Terrorist Structure established by the SCO. Based on the results, it is concluded that the Shanghai Cooperation Organization is one of the most effective organizations in the field of combating terrorism due to the presence of specialized structures, such as RATS, and various legal documents.
