(1) 1.4 billion population base , most of which have been taken out of poverty during the past generation ( positive momentum)
America did that. They ensured, at their own cost, freedom of navigation of the world's trade routs after the war and [under the false assumption that China would become a world citizen like Japan] turned a blind eye to IP theft and protectionism. Those days are over. Trump made a lot of noise about this and the dems screamed but Biden has largely left sleeping dogs lie.
(2) a command economy that can quickly react to global financial crises (eg 2008/09)
Are you saying the the rest of the world sat on their hands and didn't inflate... inflate?
Big, yes, but you can only sell so many TVs and washers and with a narrowing price gap alternatives are available. The US's avowed enemies have no choice but to trade with them.
(4) a well defined / long term economic plan (BRI & Made in China 2025) (this resembles a mega corporations strategic plan)
BRI resembles Evergrande, more debt than they can hope to recover.
(5) $3.2 Trillion foreign reserves to protect itself against recession, etc.
