As usual, another Chinese person who is overly humble and cautious. There is a time and place for it, now isn't it.
Look, China is already helping Iran. It isn't waiting around. There has been repetitive flights of supply planes with transponders shut off flying into Iran. We don't know what they are carrying. If anything, Iran might already be using radars, air defense missiles assembling missile parts together. I think the Chinese govt. understand the existential nature of this war and if Iran falls, it will deeply hurt China. So they are already acting on it, but doing it quietly as usual.
