Thanks for the links. The Economist is a paywall, but the wiki’s always a good read.
This article from Columbia is a good read as well (and no paywall). It brings up a good point that the volumes are down to “around a third of their pre-war levels.” Which makes more sense than how the OP was presenting things. No way you’ll simply halt that kind of economic relationship so quickly. But they go on to say that transit flows are still very much at risk.
I guess I’m just trying to point out that Ukraine is very much at war, but both belligerents depend on each other economically, which certainly defies expectations, as they say.
