It’s going to take a long time for international companies to get the yuan/cips/China bank corridor working, those relationships don’t get built quickly and most places that aren’t dealing directly with China don’t bank there (as opposed to the UK, Ireland or other countries that act as banking nexus’.
Those Chinese banks can’t even be used for traditional style fx management because you’ll have to double fx from local currency to yuan and yuan to ruble. The yuan fx scene is much less efficient and liquid as well.
What this more likely does is set Russian & Chinese firms to trade with each other. That looks a lot like the North Korea relationship.
