Considering India and the Saudis get around sanctions by importing Russian oil/gas and selling them on as their domestic product (either as crude or as a refined petrochemical), any indication China would do more of the same? They could buy Russian hydrocarbons at a contracted discount below market levels and sell them on globally, in ever greater amounts, and pocketing the difference for the hassle.
The same could be down with any other Russian export commodities or products, that get soft or hard sanctions imposed upon them.
