The Russians are using Roubles and allowing trade in Yuan from China. China is rotating in companies into Russia that already have western sanctions against them or have minimal Western exposure, specifically PLA owned companies.
Another thing is that China is having serious port issues right now due to “Covid”. So any tarrif lift isn’t going to have an effect anytime soon. It also doesn’t go far enough as many of the tariffs remain in place.
Finally it appears that this will end by the end of summer, so Europe will crawl back to Putin’s energy pipeline before winter.
Sounds about right.
