Both countries are opportunists that seek to fulfill their own wants and needs first. There would be only an "alliance" between them if that alliance was of mutual benefit, which isn't likely. China isn't really satisfied playing patty-cake with Russia because it wants, and has stated publicly, that they want to supplant the US as the premier power in the world. The ChiComs wouldn't want a hanger-on like Putin necessarily.
But I can see where China would want to sucker Putin in to some sort of "relationship" without really giving in to what Putin wants, which is to reestablish the Soviet Union.
In reading Schweizer's book, Red-Handed, it's becoming clear to me that China has infiltrated many of the so-called "secure" systems that accompany US technology, including military applications. Many US politicians, including #SharterJoe, Dianne Feinstein, and even GWB's brother Neil have been and are in bed with the ChiComs.
Let's not forget Swalwell, who STILL sits on the House Intelligence committee.
Lots more name-dropping in the book, and I'm just finishing up Chapter 2, which is entitled "The Bidens."
According to Schweizer, the ChiComs have paid Hunter Biden (and his associate "The Big Guy") more than $31 million while #SharterJoe was Veep. Another interesting tidbit about Joe and his habit of scheduling "off the books" meetings at the WH, not to mention Hunter Biden's declining Secret Service protection on his many, many trips to China. He didn't decline that protection when he went to Europe - only China. What's that telling us?
The elite class are being paid handsomely by the ChiComs for intelligence, information, and access to those at or near the top. They are well on their way to being the world's biggest superpower, largely because of the greed of the political and big tech elite class.
