According to the Chinese law (that's what i understood anyway), in order to run Baidu PPC, you have to hire a local agency, only thrugh them you cam advertise.
Just note that Baidu don't have an English interface (at least not one any of us non Chinese can use), and their editor is crappy as hell, but does have an English interface.
I used to work with I-Click, if it helps you, they took 10% from my spent budget as a fee.
Study hard before launching your first campaign, they have some weird things like different QS for mobile and desktop, and their matchtypes are completely different than what we know.
Also, the finance industry requres a special account (most of the accounts can't run keywords like: Forex or Trading). There's one more industry with limitations but I can't remember what is it.
