The main question of article is that: what idealist interests in china foreign policy has been marginalized in the course of time? The hypothesis of author is that: fragility of national security is a key factor in strengthening pragmatic signs in china foreign policy. This fragility is the effect of continuous security threats in domestic, regional and systemic levels. So that, author believes that national security has a big role in china's foreign policy priorities. In this situation, china has transformed from a revisionist and revolutionary actor to a conservative one, which is compatible to current international order. Although China is opposed to American unilateralism, but doesn't want to pay big costs to contain it.
