China’s implication in regional and global counterterrorism affairs has been increasing and developing after September 11^th, 2001. The potential for international cooperation in this regard, specially between liberal countries and China, is affected by normative and methodological disparities and, beyond that, relative unfamiliarity about China’s conceptualization of the issue itself. A corpus linguistic analysis of National Congress of the Communist Party of China provides a general understanding of China’s general discourse that, followed by an observation of its representation of terrorism, allows us to understand the interrelation between them. This study, therefore, evaluates the real possibilities and limitations for cooperation between liberal countries and China in counterterrorism. It offers a general view of the evolution of China´s counterterrorism discourse as a legitimizing tool for particular national and international policies that go in line with its ¨Party State¨ system. The importance of this study, therefore, lays on its direct relation to international and human security.
