UNESCO adopts as a program task to "ensure the development and free expression of all cultures around the world, each of which builds on their own roots, and its prosperity can be achieved only in contact with other cultures." So the dialogue of cultures becomes a new sense in the context of globalization and international political context.
UNESCO pays particular attention to cultural heritage: as a key element for strengthening regional and global cooperation, this heritage in all its forms of expression must be preserved, developed and passed on to future generations as a testimony of human experience and aspirations, so as to promote artistic creativity in all its diversity and to inspire the pursuit of genuine dialogue between cultures.
Nearly thirty years UNESCO works with all countries in the world to find out the cultural and natural sites, which can be designated as World Heritage, and to ensure their preservation for future generations. These are unique and diverse natural and historical places and cultural monuments, masterpieces of intangible cultural heritage.
