China calls on both sides in Syrian conflict 'to unconditionally end violence' The statement said China supported the United Nations' leading role in coordinating humanitarian relief efforts and was ready to provide humanitarian assistance to the Syrian people. But it added: "We oppose anyone interfering in Syria's internal affairs under the pretext of 'humanitarian' issues." The international community should respect the independence, sovereignty, unity and territorial integrity of Syria and the right of the Syrian people to independently choose their political system, the statement said. It said China did not approve of armed interference or pushing for "regime change" in Syria, and the use or threat of sanctions did not help resolve the issue. China and Russia joined other U.N. Security Council members on Thursday in expressing "deep disappointment" at Syria's failure to allow the U.N. humanitarian aid chief Valerie Amos to visit the country and urged that she be allowed in immediately. China and Russia have twice vetoed Security Council resolutions condemning Damascus and calling for an end to the violence, saying Western and Arab nations are pushing for Libya-style "regime change" in Syria. Russia, China and Cuba voted against a resolution adopted overwhelmingly on Thursday by the Geneva-based U.N. Human Rights Council which condemned Syria for violations that it said may amount to crimes against humanity.
