Bad for Russia China relations. Perfidious Russia will be too eager to reunite with the West and be allowed to reexert its influence over Central Asia again.
While I agree that would be the prevailing hot-take based on the recent USA election outcome, I doubt the Russian political class would be so eager to "reunite" with the West as there is no telling what happens in another 4 years (or less) and whether the Trump administration will be able to convince rest of the NATO that Russia is a rehabilitated friend in those 4 years. Vicissitude in US foreign policy is simply too great for Russia (a declared-adversary to the US) to contemplate for any permanent rapprochement. If anything, an arm's length, incremental approach will be taken by both sides. And that approach can be easily derailed during this process. What Russia does know, at this point, is that China is one of the few countries, at this juncture, that has stuck with her despite sanctions and threats. And I don't think she will give up this real relationship for some shiny promises in the future. Russia did trust in those shiny promises at one time, but it will probably be much less trusting this time around.
