He said this during a briefing at the White House.
“If Russia invades Ukraine, it will become a pariah for the international community,” RIA Novosti quoted him as saying.
According to him, in this case, Russia will be isolated from global financial markets and deprived of access to sophisticated technologies.
Singh also threatened Russia with an outflow of capital, growing pressure on the ruble, and a surge in inflation.
He also stated that in such a case, higher borrowing costs, "economic contraction and erosion of productive potential" are likely.
Earlier, White House press secretary Jen Psaki said that the United States is considering a series of sanctions against the close circle of Russian leader Vladimir Putin.
Prior to this, US Senators Chuck Schumer, Mitch McConnell and the heads of the committees prepared a resolution on the full support of sanctions against Russia in the event of an escalation of the situation around Ukraine.
