Pakistan has had a western nation rule over it before and it didn't exactly go well. It's also not exactly a well-run nation that can tweak a few things to solve excesses like with antibiotics. Warnings about the overuse of antibiotics go back to the 1950s. This isn't something that will come to a surprise to anyone, and it isn't even an impossible challenge to overcome.

Here in the Netherlands, antibiotics usage in the meat industry was absurdly high until a bit over a decade ago, despite decades of warnings. And as a side note, I would classify the way the country has been run for all of my adult life as poorly governed, with elected officials constantly lying, government parties trying to work around the law rather than comply leading to several crises, and just general mismanagement. It's not Pakistani army bad, but it certainly warrants warnings from other countries.

As for Pakistan: If I were their leader, knowing about things like vaccination centres ran by the CIA to secretly hunt down and kill Taliban soldiers in search of Bin Laden, I'd be wary of warnings coming from the West. I wouldn't much trust foreign charities to install clean water infrastructure either, because that's far from the only time they've been used as a front.

Are your leaders listening to the warnings coming from Bejing, Brussels, Israel, the Kremlin, and Washington? Would you even trust what they say is in your interest? I wouldn't exactly put it past foreign intelligence agencies to spread typhoid in areas of interest just so they could come in and "help cure" everyone.
