That is absolutely not reflected in their currency. They do way way better than western media attempt to make everyone believe.
You call that Iran cat and mouse game a success? It's an absolute farce that keeps one of the great nations of extremely highly educated people with a rich history and culture under the thumbs of Mickey Mouse.
The currency is artificially propped up and the current rate is meaningless. You can only buy it but selling it is near impossible. Russian CB is also spending reserves to prop it up. If selling was permitted, it would drop fast and hard.
Replacing EU pipelines with China will take at minimum 3 years. During that time there's nothing to do with all this gas supply but sell it with a large discount as LNG to China and India. The amount will be a drop in the bucket compared to what they supplied to EU though.
I don't agree with the Iran sanctions but they were effective, very much so.
