To be fair, Swiss agriculture is so heavily subsidised that it makes French agriculture look like a bastion of free market liberalism. If the Swiss were to expand it further to make more exports to Russia, that would make them poorer, not richer.
I see that places like Argentina do seem to be attempting to sell things to Russia in response to recent developments. I wish them luck with it, honestly, and this might be good for Russian consumers from the perspective that Argentina does, at least, produce some decent cheeses.
On the other hand, doing business with Russia is likely to be a nightmare. Just like doing business with Argentina. Possibly they deserve each other.
