“It is not in our interest to announce our actions in advance, which will give Russia the opportunity to take steps that will allow it to reduce the impact of sanctions,” he said.

During the briefing, White House Press Secretary Jen Psaki confirmed that the US authorities had prepared sanctions lists of representatives of "Russian elites and their families" in case of "aggression against Ukraine."

As the Financial Times newspaper previously reported, the United States has prepared a list of persons “close to Vladimir Putin” against whom sanctions may be imposed due to the aggravation of the situation around Ukraine.

The list of individuals includes people "playing a role in government decision-making."
