With the deepening of globalization，international tourism becomes more and more convenient. Cultural heritage as one of the core contents of the tourism industry attracts tourists all over the world. The Palace Museum，as China’s symbolic Cultural Heritage，embodies Chinese cultural characteristics，builds Chinese cultural identity with intensive historic elements. Nowadays we emphasize the international communication of Chinese culture，most of the efforts are “external”，that is，send Chinese culture abroad. However，the “internal drive” has been neglected. If internal and external efforts are dynamically integrated，effective implementation of international communication Chinese culture can be achieved. There are at least five perspectives for the Palace Museum to promote the international cultural communication of Chinese culture. They are digital Museum，foreign language strategy，international cooperation，creative design and educational function，which all work together effectively to promote the overseas dissemination of the Chinese culture. China cultural heritage tourism resources are numerous and attract more and more overseas tourists. But some of the cultural heritage scenic spots are excessively commercialized. The awareness of cultural relics’protection is not strong. Foreign languages are not adequately and properly used. The communication modes are out of date. All these hold back the validity of the intercultural communication of Chinese culture. The valuable experience of the Palace Museum making full use of the internal drive is worth learning for other Cultural Heritage sites to effectively promote the international communication of Chinese culture.
