And by the way, general consensus in the Russian population is that sanctions (especially in the banking and foods sector) would be good for Russia, forcing the government to finally build up domestic production and generally become more centred on domestic needs.
Russia imports almost everything and exports only Petroleum, Gas and Metals.
So the options will be:
1. Import everything from China
2. Reduce imports, rise excise duty and encourage domestic production.
The 2nd option seems the better one for me. But it is up to Putin to decide.
