"We confirmed to our US partners, who sent us the draft memorandum, that we were ready to participate in the negotiations. Not only issues related to iron are extremely important for us, but above all - the principle. We should look for those principles that work while making complex decisions", Rogozin said on Tuesday.
In 2017, NASA and Roscosmos concluded an agreement on the joint creation of the lunar orbital platform, known as the Deep Space Gateway, at the 68th International Astronautical Congress (IAC) in Australia's Adelaide.
However, later, Rogozin said that Russia could not participate in the project as, under the agreement, it was set to create only a gateway module and life support systems.
In addition, he said that the US was interested in exploring the lunar orbit, while Russia sought to study the lunar surface.
