In the recent NBC's Face The Nation interview Top Treasury official says U.S. sanctions would target Putin, Russian economy after the 2 minute mark US Deputy Secretary of the Treasury Wally Adeyemo said something about technology that I thought was interesting.
Q: But how effective can US and western sanctions be if Russia is just going to move closer to China, as we're seeing.
Adeyemo: So Margret I was in the Obama administration in 2014 when we took actions against Russian in response to their invasion of Ukraine we've learned a great deal of lessons and what I can tell you is that the actions we would take if Russia were to invade Ukraine this time would be far more significant.
And it's up to President Putin if he wants to become dependent on China going forward, but what I'll tell you is that China can't give Russia what they don't have. There are critical technologies that Russia is dependent on - the United States and our allies on, technologies that China does not have access to.
Question: Which "critical technologies" does Russia dependent upon the United States and its allies for, that "China does not have access to?"
