Nobody is blockading China. Nobody would dare. Biden just said he's fine with slavery in China, he won't so much as voice a negative opinion about their human rights atrocities. The Europeans aren't much better. Absolutely nobody is blockading them. The Saudis and Russians will sell China all the oil it cares to buy, and the Russians can deliver it via pipeline trivially.
Besides that, they're not going to need most of that oil in ~20 years.
Quick question: what has happened to China as a result of what they did regarding the pandemic? Millions of people just died, along tens of trillions of dollars in economic destruction. They lied about the pandemic, they hid the outbreak as long as they could, they're still hiding information about its origin and the early days. Barely anyone even cares to dispute that, they all just shrug about it. Where are the sanctions? Where's the blockade? Right. Nobody dares. Barely so much as a squeak in their direction. If I'm China I'm starting to ask: well then, what else can I get away with so easily?
Let's see here. They don't care when I enslave 500,000 people to pick cotton. They don't care when I commit cultural genocide and put millions of people in camps. They don't care when I violate prominent international agreements at will and strip Hong Kong of all of its rights. They don't care when I support a military dictatorship and coup in Myanmar. They don't care when I prop up and enable a crazy nuclear dictatorship in North Korea. They don't care when I destroy Tibet and culturally strip the entire nation. They don't care when I annex territory the size of France - from numerous of my neighbors - in the South China Sea by military force. And so on. (and before anyone bothers, that I pointed out these facts about China doesn't simultaneously imply the US is The Good Guy, I'll save someone that logic failure)
But oh boy, the world is suddenly going to care about Taiwan as China begins their annexation formally. The buck stops there, no doubt about it. Un huh.
Before another 10-15 years goes by they're going to have the world's most powerful military overall (they'll still lag in tech in some areas). It's exceptionally obvious. The US can't afford to continue its global projection, it's rapidly weakening (courtesy of the extraordinarily stupid decisions it has made fiscally over the past 20 years), and China is just beginning its global projection phase; one will contract, one will de facto conquer the world. The pandemic helped tip the US over fiscally into a more rapid downward spiral, it pulled that future forward by a lot.
Have you seen China's export machine during the pandemic? They took market share. They've become far more potent economically while their competitors have been severely weakened. As a future bet, who's taking Boeing versus China at this point? Intel & Co. vs China's future in semiconductors? The US is in a very bad position.
Within that 15 year span of time China will be sailing aircraft carriers past Hawaii and off the Pacific US coast, as a show of force, which the US will be entirely unable to stop.
I've rarely seen anything more obvious geo-politically than what is about to happen regarding China. Asia is theirs, absolutely nothing can stop that outcome. They'll even compete toe-to-toe in Latin America for influence, right in the US backyard (as we have been doing in their backyard for so long). The best the US and its allies can hope for is to hold some political & economic ground in Asia and not be entirely neutralized in the region.
The age of the American superpower is over. Act accordingly. The only thing the US is good for now is resource - wealth - extraction, while it lasts (debased by the minute). Then, afterward, get out while you can. Go somewhere nicer, somewhere sane, somewhere with a functional government, a decent culture, a future of prosperity and reason - that isn't the future of the US.
