With the promotion of the Belt and Road Initiative，Internet technology has provided a more diverse way of communication for Chinese diaspora media. The official website of Chinese diaspora media can present more reports with richer contents to the public，but it does not meet the expectation of interaction. Generally，the Chinese diaspora media that base in the countries on the China-Indochina Peninsula Economic Corridor regard Chinese public as the primary audience of their social media platforms，and they construct the Chinese national image through one-way communication by official websites and interactive communication by social media with the Chinese public. Thus，the infrastructuralization is not synchronize with the platformization for these Chinese diaspora media，which has resulted in their incapability of spreading Chinese stories to the outside world. Although these Chinese diaspora media are mainstream Chinese diaspora media with relatively large circulation to serve overseas Chinese in the countries to which they belong，their roles of constructing Chinese national image remains to be strengthened if we place them in a broader and international perspective.
