ECO cultural sphere is one of the rare civilization and historical treasures of human society. This rare legacy is the fruit of years of joint intellectual efforts by regional communities forged into a synergy to evolve in the form as we know today. Taking stock of the contemporary world challenges and obstacles the current article seeks to investigate the question as to what approach could be used to study the cultural and historical legacies in the ECO region in order to render a fresh outlook on cultural life of the communities present in this intellectual realm? The research method has been that of a conceptual-functional effort to assess the concomitance of historical and cultural constructs in these communities based on juxtaposition of the two forces of continuity and change. The findings suggest that if strategic plans are in place to formulate a cultural diplomacy for the communities in this region, a promising bright future of interaction and cultural excellence will provide a basis for expanding political and economic relations, which in turn, will promote the individual and collective security, stability and development of the nations in this region which ultimately enhances their standing in the world.
