China is calling for a united Syria and is encouraging parties to the six-year conflict to work hard together toward a peaceful resolution.

Chinese Special Envoy for Syria Xie Xiaoyan reiterated his country’s position during his visit to Tehran where he met with Iranian officials.

He added that it was Beijing’s unwavering position that Syria’s sovereignty and territorial integrity be maintained.

China has long urged that all parties in Syria must effectively implement Security Council resolutions and that the international community should work simultaneously on the tracks of ceasefire, political negotiation, humanitarian assistance and counter-terrorism cooperation in order to promote the peaceful resolution of the civil war which has killed in excess of 400,000 people, according to UN estimates.

Xie was in Tehran from July 20 and left early on Sunday in a trip that stressed bilateral Chinese-Iranian ties and examined means to resolve regional crises.

“Iran is an important country in the Middle East which has a significant and unique influence on the Syrian issue,” he said.

He told reporters in Tehran that China had provided about $100.5 million of humanitarian aid to the Syrian people.
