In their international communications，Chinese mainstream media are moving toward micro video，which is playing an increasingly important role. In the meanwhile，the micro video platforms of Chinese Internet enterprises will start to grab the overseas market shares when the domestic market is saturated，with contents dropping down to reach out for more quality content sources. Dissemination of values is especially important for Chinese micro videos that are clinching a niche internationally，because it reflects the national strength. Without disseminating values，micro video cannot generate international influence. This paper aims at exploring into how the micro videos of Chinese media should spread values in international communications，namely，what the contents about values they should strive to into their communications. For this purpose，the paper chooses micro videos of UNESCO on YouTube as an object of study to seek the values reflected in their contents and ways of expression. The 197 hottest videos broadcast by UNESCO on YouTube from 2009 to 2017 show that UNESCO conveyed six major values：cultural diversity and plural cultural values，public welfare values，humanitarian values，rationality values，equality values and holistic values. Based on the findings，this paper tries to suggest tactics for Chinese micro videos operators in spreading values in their international communications.
