China pins hopes on China-Mongolia-Russia economic corridor — diplomat

It appears US-led economic sanctions have not isolated Russia.  By contrast, they have emboldened Russia's trading partners to form tighter ties amongst themselves.

If anything, the sanctions have isolated the US in a classic case of unintended blowback, as one country after another (including in the EU) abandons trade sanctions, and in fact, become founding members of China's Asian Infrastructure Investment Bank.
