This is not entirely true. Even the elite who were included in the sanction lists (Russian) are regularly noticed in the EU countries. They can come to rest through diplomatic channels or through bribes. Also children of people under sanctions live mainly in EU or the USA. While they are investing in those countries, they are not asked questions about the origin of the money

Then go after their offshores. Then start targeting their ties inside russian elite

> Then go after their offshores.

Nobody ever touches offshore havens since rich people from everywhere have money there.

It took 9/11 for Switzerland to not laugh at law enforcement request from other countries. (Probably still laughs to anyone thats not US and maybe EU)

> Then go after their offshores.

What, specifically, does this mean? The EU sanctions, idk, the Bahamas? Who? And how?

I mean seize illegally earned money and/or forbid them and their families spending those money in the EU and other friendly jurisdictions. EU as a whole should have enough weight to make it happen if enough political will is present.

They are already forbidden to conduct any business, i.e. spend any money, in the EU.

To literally "seize" the money stored in an offshore bank account is difficult unless the EU is also willing to march an army into those countries.
