US Ambassador John Sullivan was invited to the assistant to the President of Russia Yuri Ushakov, a source in the Foreign Ministry told RIA Novosti.
Later, the department confirmed this information.
“During the conversation, it was said <…> if the American side, against the background of Biden’s words about intentions to improve relations with Russia, undertakes new unfriendly relations in the form of sanctions, the Russian side will react in the most decisive way,” the agency’s interlocutor said.
On Tuesday, at the initiative of Washington, a telephone conversation took place between Presidents Vladimir Putin and Joe Biden. The American leader, in particular, confirmed his intention to build stable relations with Russia and offered to hold a personal meeting in a third country in the coming months.
The new US administration has already introduced several packages of restrictions against Russia due to the situation around Alexei Navalny. The White House has repeatedly stated that these measures will only serve as a start and that new sanctions will follow.
