Over 20 specialists demanded Joe Biden to present a list of sanctions in the case of a Russian invasion of Ukraine

The document emphasizes that this list of measures should be published "immediately and publicly," according to Vesti.

Earlier, Washington and its allies have repeatedly stated that they are going to impose tough sanctions against Moscow in an attack on Ukraine. At the same time, it was never announced what exactly these measures were. Unless the US was frightened by the scope of these sanctions, for example, US Vice President Kamala Harris in an interview with CBS threatened Russia with "sanctions that you have not seen before".

Earlier it was reported that the United States promised to increase military assistance to Ukraine in the event of Russian aggression, as reported by Assistant Secretary of State for European and Eurasian Affairs Karen Donfried. She said that Washington can increase the volume of military assistance to Ukraine in the event of aggressive steps by Russia.

In turn, Russian President Vladimir Putin said that the introduction of large-scale sanctions against the Russian Federation could result in a complete rupture of relations for them.
