China's stand on the Syrian crisis was not very effective in the direct influence the to the events in Syria, where it is trying to enhance its role in the Syrian file.
This role has been limited to the support of international political efforts targeted to find political solution for Syrian issue, with direct diplomatic and military support for the Syrian regime which appeared in China's use to veto in the security council four times against decisions related to the course of events in Syria, which were seeking to condemn the Syrian regime anyway, and the first was voting against a draft resolution by European proposal and an American support in 2011 to condemn the Syrian regime's suppress protests against it in Syria .
Then, in 2012 followed by a China's veto on a draft of a resolution which demands changing the regime in Syria, and in the same year, also opposed the proposed resolution that threaten the Syrian regime with sanctions if it does not withdrawal its forces and military mechanisms from cities and areas that have demonstrations against it.  The final chines veto was in 2014, against a decision aims to refer the war crimes committed in Syria to the international criminal court.
