Kerry is a really, really good dude, and I believe him.

Without going way off into the weeds, you can do some web searches on "Chinese APT41 watering hole attack". This is happening right now at a rate no one has ever seen before.

Basically, Chinese government-sponsored hackers are putting malicious software onto reputable sites. You go visit a perfectly normal website, and you get a hacker payload installed on your machine.

Somebody then uses those creds to log into a web portal. Or logs into your bank account and transfers all your money.

I'm not saying Chinese President Ji sat down and sent that email, but Kerry's explanation makes perfect sense. He's a really good guy, and one of the two best medical trainers I know.
