We can say without exaggeration that in human history there wasn’t a time when interacted simultaneously, with such a magnitude and intensity, so many State and non-State entities, so many groups, organizations and populations as nowadays. In these circumstances, an imperative of the modern world is to ensure the cohabitation of people with different cultural identities within a common milieu of life. In addition to the legislative and politic measures of states, the most effective strategy in this regard is to promote and enhance the authentic intercultural dialogue, through which cultures and people meet, know and understand each other better, obtaining a spiritual and pragmatic enrichment. In this situation, it can be achieved two important goals: protecting cultural differences and form a favourable environment for their coexistence for the benefit of human development.
