> Indeed, for filling their ~1.3B barrel strategic reserve

That's 117 days, or four months, of imports [1]. Half of Hormuz-transiting oil ends up in China [2]. So even if China fully substitutes lost imports with reserves, that's not even taking them through the end of the year. (And China running down its reserves is a strategic win for America. It means they aren't available to buffer a blockade of the Straits of Malacca.)

I don't even know of a credible economist in China arguing China is insulated from this shock.
