Russia is already heavily sanctioned. Further sanctions will mean nothing to them. They already have plenty of natural resources and China can provide them with whatever else they need. Sanctioning Russia is really sanctioning Europe from getting cheap energy. And btw Russia would appreciate getting their $300 billion back that the West is currently holding hostage.
President Trump will tariff China, India and Brazil 100% if Putin doesn’t agree to ceasefire in 50 days. That’s the meat of the threat.
