This paper discusses the emerging importance of soft power in global diplomacy from various perspectives, particularly the forms and methods developed in international cooperation, trust building, and categorizing cultural influence. Using the contexts of three case studies- Russia, India, and South Korea, this paper further elucidates how countries engage in soft power strategies from media influence, and cultural exchanges, to technological leadership in boosting their countries' global ranking. The analysis extends to how soft power works in the mold of global challenges and geopolitical tensions, where potential future diplomatic relations might take shape.
