The Biden administration and its allies are assembling a punishing set of financial, technology and military sanctions against Russia that they say would go into effect within hours of an invasion of Ukraine, hoping to make clear to President Vladimir Putin the high cost he would pay if he sends troops across the border.
In interviews, officials described details of those plans for the first time, just before a series of diplomatic negotiations to defuse the crisis with Moscow, one of the most perilous moments in Europe since the end of the Cold War. The talks begin Monday in Geneva and then move across Europe.
The plans the United States has discussed with allies in recent days include cutting off Russia’s largest financial institutions from global transactions, imposing an embargo on American-made or American-designed technology needed for defense-related and consumer industries, and arming insurgents in Ukraine who would conduct what would amount to a guerrilla war against a Russian military occupation, if it comes to that.
