You forgot the anti-vaccine campaign they ran in countries near China saying their vaccine contained pig parts. Not the US state dept's first anti-vax campaign btw.

US vaccines were made available first and foremost to Western citizens, and only then were made available to purchase. China released their vaccine worldwide, so countries without a vaccine program had access earlier and cheaper than they could acquire vaccines from the US. Their anti-vax campaign was meant to prevent other countries from accepting China's offer, thus preventing goodwill towards China, protecting the profits of US companies, and leading to the deaths of millions who could have been saved in "US Allied" countries such as the Philippines.

If you were going to buy into one of these two conspiracy theories, first you should have some actual evidence, and then you should look at the behavior of these countries and ask yourself: which behavior is more consistent with releasing a virus that could act as an economic weapon meant to shut-down a country, but not kill everyone?
