I would be interested in that analysis, as I've read the exact opposite. China will be the sole supplier of many goods for Russians as they have nowhere else to go, but simultaneously China is careful not to overstep bounds as it does not want to upset the US, a trade partner about 10 times more important than Russia. It also stopped/delayed many promised infra investments in Russia. As for allegiances, China has none. Not with anybody. China has no moralistic or principal allies. It simply does what is best for China, and happily plays all sides all at once.
