Abstract. This article explores the role of intercultural communication in a globalized world where interactions among nations and cultures are rapidly expanding. The study analyzes theoretical and practical contributions of the English language as a primary medium of international communication in education, diplomacy, business, and digital environments. It examines the relationship between language and culture, the development of intercultural competence, and strategies for reducing communication barriers. The findings demonstrate that strengthening intercultural competence is essential for promoting mutual understanding, peace, and cooperation in an increasingly interconnected world.
