The purpose of this article is to discuss about the potential impact of the Internet, as an indispensable part embedded in today’s human society, upon the international politics. There are two key points to emphasize on: How the Internet might influence the macroscopic power distribution, and how the Internet might exert its impact upon the domestic politics of a state, then influence its foreign-orientation. The article takes China as a case for study. On the one side, China’s military-based cyber-power has been developing at a fast speed estimated by some scholars, and the information technology is well utilized to support conventional military power, both of which lead to the suspect and countermeasures by other countries, and there might be a security dilemma based on the information technology, similar as any other technologies in the history influencing power distribution. On the other side, the Internet also motivates China’s development of economy. However, it makes less impact upon China’s domestic politics, as the public tends to be accustomed to the narratives and images projected by the government, whose mechanism will be focused on and illustrated in detail in the article. The situation of the Chinese Internet determines that an “information-driven democratization” is not likely to happen in China. The authoritarian operation of the Internet guarantees China’s political order to a degree, but it might reinforce the divergence of the identity and interests between China and democratic countries represented by the United States. In China’s special case, the Internet plays a pessimistic role in its foreign relations on the whole, referring to three major theoretical frameworks of international relations research.
