The signing ceremony was part of a visit of Vietnamese President Nguyen Xuan Phuc to Moscow. It was attended by Russian Deputy Prime Minister Dmitry Chernyshenko and Vietnamese Deputy Prime Minister Le Van Thanh.
Another agreement was signed by the RDIF with Vietnamese investment group Sovico Group and Vietnamese pharmaceutical company Vabiotech, which already produces the Russian vaccine, to bring the bottling and packing of Sputnik V and Sputnik Light, its single-dose version, to Vietnam.
"The RDIF is currently collaborating with Vietnamese regulatory authorities to authorize Sputnik Light," the Russian sovereign wealth fund said.
Sputnik V was granted emergency use authorisation in Vietnam on 23 March.
