The article explores the development of Iran’s foreign policy within the transformation of international relations on the example of the Latin American tour of the President of the Islamic Republic Ebrahim Raisi, which he made in June 2023. The paper identifies main areas of Iran’s interaction with key partners in the region: Venezuela, Cuba, Nicaragua. The reaction of the US and European media and analytical circles to the aforementioned tour, reflecting the main concerns of the US political leadership regarding Iran’s growing political influence in the region, has been analyzed. The author’s assessment of Iran’s prospects for expanding cooperation with Brazil and other Latin American states is given. The efforts of the Islamic Republic to join BRICS are noted. It is concluded that Iran’s actions in Latin America are in line with the general foreign policy concept, which implies strengthening the position of the Islamic Republic as one of the leading states of the emerging polycentric world, seeking to overcome the isolation organized by Western countries and maximize the competitive advantages of its geostrategic position.
