Why was Russia excluded from a joint virus project?
I don't know. May be high risk of leaking information (Russians often don't care about signed NDA, especially if there is something important), may be low technology level of Russia, or may be they are really not excluded at all, especially if you take a closer look at all that "make harmless vaccine in a month" crap. In any case Russia is a member of WHO and have to obey their "recommendations".
