I don't know why you read too much into what Chinese FM said in that statement. It has been China's position that it won't sell weapons to both Russia or Ukraine during this conflict. Western MSM has tried to corner China on this issue but with no available. Beside, Russia doesn't need Chinese weapons unless it wants to mobilize million of troops. With dual uses component from China, Russia is capable of sustaining the war with its own defense industry.
In addition, China is also sending its DM to Russia for a meeting for further cooperation. With meeting with Lula underway now and other countries' leaders in the coming weeks and months to draw a roadmap of de-dollarization, I think China would lay low a bit but push for military and economic engagement. BRICS and SCO would see a big push from China to fight back the West. Belt Road would revitalize and weaponize towards same goal.
