RDIF is a key Russian investor in test systems to detect coronavirus infection, anti-COVID medicine as well as in Russian vaccines Sputnik V and Sputnik Light.
Earlier, US President Joe Biden directed the Treasury Department to completely block the Russian Direct Investment Fund (RDIF) in the coming days.
