Do y'all think the West missed an opportunity to bring Russia into the system so to speak after the USSR fell? That was rough times for them and under those conditions a guy like Putin has a nice smooth runway. Not unlike Adolf's situation in Post WW1 Germany.
And now on the contrary we have China, who prospered beyond their wildest dreams since joining the commercial community and despite all of that seems poised to go down the bad path.
Almost seems there are no lessons to learn from history, LOL.
I actually recently saw some opinions specifically about your question. I'm not expert enough to judge whether it's true or not, but I can at least paraphrase. As I understand it, here's the answer: "We tried it."
The prime directive of the Chinese Communist Party is a monopoly on power. Nothing trumps that. For a long time, economic growth and connection with the West was compatible with that goal. With the growth of the economy and the rise of private(ish) enterprise and a middle class, however, came political pressure. Large business owners started wanting some influence on policy. Since that threatens the Prime Directive, it must be throttled. That's why we see big business owners disappearing, imprisoned, stripped of their assets or position, etc. in China.
You can apply similar thinking to Russia, although the goal there appears to be enrichment of the few, along with protecting the power of the mob that rules Russia. After 1989, attempts were made to bring Russia into the rest of the world. Europe started importing a whole lot more petroleum products. Lots of tourism to Russia, etc. All of this was compatible with the Russian ruling class's goal: personal enrichment and empowerment. If you go back 15-20 years, the flow of information, immigration, and commerce started shifting attitudes towards more westernization. The former Soviet bloc countries were getting better relationships with the rest of the world. All of that poses a threat to the Russian ruling class. And so it had to be stamped out. Chechnya, Georgia, the various 'stans, and yes, Ukraine, had to be kept in line.
In the long term, I personally think Putin lost one week after his troops marched into Ukraine. Russia already experienced a huge brain drain when the USSR broke up--much of their technical expertise was in Ukraine--and it's happening again. Anyone who had the brains and money to do so, left Russia at the beginning of the war. Stack that on top of the 460k casualties (perhaps half of which are dead) and Russia's already-teetering population pyramid, and Russia is in deep trouble in the long term. Unlike the US, they never had much immigration. I lived there for a couple years around the turn of the century, and there's a whole lot a of racism. Not universal, but pervasive and intense. You don't want to be a black person in Russia.
Russia's arms exports have cratered, and they ain't coming back for a long, long time. Even if Russia succeeds in conquering Ukraine, *and* if other countries wanted to buy their stuff, *and* if they avoid sanctions, Russia will take
years, if not decades, to rebuild everything they've lost before they have enough capacity to export to other countries. They've enacted a wartime economy, stripping workers and resources away from other industries in order to support their war. They're printing Rubles like there's no tomorrow. Their oil and gas exports are *way* down. They're going to be hurting for a long, long time, regardless of the outcome in Ukraine.
