The Antonov 124, like it's Antonov 22 prop-driven predecessor, was originally designed primarily as an ICBM carrier, to move them round the Soviet Union from the central missile base at Tver (halfway between Moscow and the old Leningrad), where the remaining Russian Air Force fleet is still based. They would fly them to dispersed airfields from where Mil-12 (very) large helicopters would take them individually to sites hidden in the forest. Commercial airfreight haulage for the An124 came later.
Due to this, it is unlikely that RR or GE, both from countries where said cargo was doubtless targeted, would be particularly permitted by their respective governments to supply engines for such a craft.
Incidentally, the Antonov design organisation was, and still is, a Ukrainian company, not Russian.
