So because China didn't send arms the day Putin and Xi met you conclude there were no promises made? That is extremely weak logic.

I'm not saying that such promises were made. I repeat that we don't know what was said behind closed doors, and both Russia and China are very close-lipped about such things.

Publicly Russia and China are closer than maybe ever. BRICS+ and America's ham-handed approach to both Russia and China is pushing Russia and China closer together.
