Kamala Harris (US Vice President) making some statement on the Russia and Ukraine problem said US and her aligns will impose unprecedented economic sanction on Russia if they continue to evade or attack Ukraine. So I'm wondering what kind of unprecedented economic sanction can be given to Russia if they continue to evade Ukraine.
We have already seen these sanctions is on the banking, energy sectors mostly. But EU countries like Germany, France is not agreed to putting sanctions on Russian energy sectors and without putting sanctions from all the EU countries it won't be effective. The USA could impose any many sanctions as they want but Russia's main market is from Europe and that's where they have the upper hands the USA.
