No official statement I can find. Frankly I think part of the confusion is stemming from the idea that the Geopolitical Game of Thrones has ‘stopped’ as it were.

And that Russia, China and others are going to stop pursuing their own national interests, and situations that benefit themselves at the expense of the U.S. just because we share some mutual enemies at the moment.

Expanding their foothold via backing opposition to the U.S in South America is ultimately a net benefit for them. Irrespective of what Venezuelans want. As it can be a reasonable assumption. Bolsonaro or a later Successor will resume aligning Brazil with the U.S when Trump resumes Office. Threatening their inroads in South America. Should Bolsanaro run again or reassume Office.

Footholds in South America could just as easily be expanded into Basing Rights. Allowing Russia to forward position forces, such as Nuclear Forces, to threaten the Southern U.S. A Potent political tool for negotiations.
