Just to play Devil's Advocate.
What if I said back in 1950s:
"I don't think China will have an option to "abandon" the Soviet Union. China is hugely dependent on Soviet technology, assistance, and the West HATES China and full-scale embargos on China. Most Chinese don't trust the Americans, and in fact, I have some Chinese friends here that hate Americans,..... yes "HATE""
and then Nixon happened, US-China quasi-alliance against Soviet Union, and Soviet Union collapse. What's preventing a Reverse Nixon? Hatred alone and economic ties wasn't enough to stop China from becoming quasi-allies with West/US against Soviet Union. Anything can happen. Esp. since Russian billionaire oligarchs are Westophiles (see their mansions in London) and potential discord over Central Asia/Artic sphere of influence.
I don't think you understand the dynamics. Nixon didn't cause China to turn against the Soviet Union, the Sino-Soviet split happened long before.
Today, both China and Russia are careful to cultivate a friendly relationship.
