You don't have proper facts to discuss Afghanistan or Syria. China is far removed from both conflicts.
Right now Assad is slaughtering 90% of his Syrian population who are resisting his regime, due in large part to sectarian militias which Iran placed in Syria to back him up. They are running torture centers for Syrian women and children to use to demoralize Syrian resistance. Rape and sexual violence is being used actively by the regime and its supporters, yet you feel the need to take the side of this tyrannical regime.
I always disliked Assad, from the beginning when his Atheist genocidal policies became apparent, long before the the Syrian students took to the streets to demand right to govern themselves.
Bashar is a kind of monster who took money from the US to torture and abuse people whom the US caught and accused of terrorism, which ran in tandem with Bagram, Abu Ghareb, and Guantanamo.
He is not a Shia, nor even a Muslim, but an evil man who will go to any means to stay in power, even when the majority of his people want him to go. He will play and use any power for that purpose, previously it was US, then Iran, and now Russia.
I am very indignant about the conduct of Chinese members on this topic. You are supporting a regime which is committing mass genocide on a religious group by any means available to them. This will make relations very difficult with China for the 85% of the Muslim world which is Sunni and 87% Sunni Pakistanis. Think before you put your eggs in the wrong basket.
Russia and Iran have historical hatred against Turks and Sunnis, so their conduct is understandable. China has no such problem, therefore bad policy has no excuses.
