Ushakov confirmed that Biden had mentioned possible sanctions measures during his talks with Putin.

“What has been said before publicly and communicated through various channels to us, has now been said, but in a fairly acceptable form, which is worthy of the presidential level,” said the assistant to the Russian leader.

According to Ushakov, Biden also hinted during negotiations with Putin that the United States may allow Russian diplomats to access the confiscated diplomatic property to assess its condition.

US Undersecretary of State Victoria Nuland said during a congressional committee hearing that the United States is discussing with its allies a sanction option that would be tantamount to completely isolating Russia from the global financial system in the event of a Russian "invasion" of Ukraine.

Jake Sullivan, Adviser to the President of the United States for National Security, admitted the possibility of using Nord Stream 2 to put pressure on Russia.
