The same China that's currently saber rattling at every single direct neighbor they have? The United States Used to Know the value of soft power too. But it's the nature of states. They always corrupt. And the corrupt don't value soft power or diplomacy.
And don't bother trying to argue that China isn't corrupt. Billionaires and millionaires exist there. Allowing that from the start was a corrupt move. Don't question that the state doesn't covet that power. Just because they will imprison or kill those Millionaires and billionaires if they cross "the state". Does not make them uncorrupted.
As to the tanky bit...... Honestly outside of the horrendous social policy, China has actually done a number of things right or at least better than the US, which isn't a great achievement. I honestly wouldn't mind discussing and dissecting those things if it wasn't for disingenuous defense of their cultural and social abuses by them or the ML. That think the world will be a better place if they were the bully. Without understanding that who the bully is, isn't the problem. It's the existence of said bullies.
