On the 13th local time, Russian Deputy Foreign Minister Ryabkov said that he was studying inviting US Deputy Secretary of State Nuland to visit Russia to allow him to explain the activities of the US biological laboratory in Ukraine.
Ryabkov said the U.S. has so far failed to respond to requests for information on Ukrainian biolab activities.
Russia believes there is no point in formally engaging with the United States on the situation in Ukraine, and the United States is "wholeheartedly" helping Ukraine and supplying it with weapons.
Russia sees U.S. and NATO vehicles transporting weapons on Ukrainian soil as legitimate targets.
Attempts by the United States and Western countries to delay Russia's special military operation in Ukraine will not succeed.
The U.S. has also used the situation in Ukraine as an excuse for refusing to engage in security talks with Russia, which Russia has taken note of.
Ryabkov pointed out that the West is blocking investment in Russian government bonds in an attempt to provoke a Russian debt default.
He said that Russia is one of the world's leaders in advanced technology, and U.S. sanctions pressure will only slow Russia's development, but not stop it.
Against the backdrop of U.S. inflation, the stability shown by the Russian economy and the effectiveness of measures to stabilize the ruble exchange rate has angered the United States.
The U.S. is prepared to sacrifice its own companies, which are leading investments in the Russian economy.
Under current conditions, Russia will not be closed to the outside world and will remain open to the United States.
