>but obviously the Russians did no such thing on their side

Why obviously?

The USSR invited cosmonauts from all over the world to fly and work at the Salut-6, Salit-7 and Mir stations.[0]

That's France, Britain, Austria, Japan, India, Soviet block countries, Mongolia, Vietnam, Syria and Afghanistan.

USSR, yes. But the ISS was launching during a time when USSR no longer existed and Russia was fairly isolated. Hence, "obviously": US at that time had many close allies, but Russia had only a few, and not as technologically advanced.

>Russia was fairly isolated

Quite the opposite, the West welcomed weak and crumbling Russia. To a limited extend, of course, but still Russia joined G7 and many European organizations. Western companies were busy buying privatized Soviet assets pennies on the dollar.
