“We are also very closely coordinated with our European allies on this issue at the level of deep specificity,” RIA Novosti quotes Sullivan.

He noted that in order to develop an appropriate package of measures, experts from the Ministry of Finance, the State Department and the National Security Council communicate daily with key capitals and Brussels.

“But I think it’s not beneficial for us to lay out specific details now from this podium,” added Sullivan.

Earlier, a spokesman for the American administration said that the United States is not looking for a conflict with Russia, but is ready to respond to "destabilizing actions."

At the same time, US Undersecretary of State Victoria Nuland informed about Washington's discussion with its allies of the option of sanctions, which would be tantamount to complete isolation of Russia from the world financial system in the event of a Russian "invasion" of Ukraine.
