The only similarity I see is that neither Xi nor our Narcissist-in-Chief brook any criticism; but aside from the "Let 1,000 Flowers Bloom" campaign of Mao, that has always been China's domestic policy.
China, unlike the US, can look 10 years into the future and consistently execute towards a goal. That's not because of leaders, it's because the systems are fundamentally designed this way.
It's like the two party system in the US. It's because of first past the post in the Constitution. The system is designed to do this, so it does it. The US is designed to be unable to plan or execute long term vision.
Though how did US managed to be long term thinking since world wars up to ~1980s or 90s? Was it just generational trauma of world wars that allowed to align opinions between parties? And by trauma I mean some combo of real trauma to not have WW2 again to the capitalistict and globalistic drive to be world’s hegemony.
I think this is why FDR was a successful president and was able to get so much done. He had 3 complete terms and a partial 4th term.
If you are going to have shorter terms you need to have your successor continue with your plans, but in a liberal democracy you don't know who is going to follow you. Even if your party wins, your successor might not continue with the plan.
At least from my experience I would say change of government won't lead to cancellation of a project or reform just an expansion or contraction in scope.
You can't do something like implement a 1 child policy and stick to it for decades causing a demographic collapse because it wouldn't have broad appeal from the population.
