If you are a US citizen then you need a visa. You also need an invitation letter from the business in China, a letter from your US employer, and a passport that is good for at least 6 months after the initial stay. Then you need to fill out the application. Travisa can help you with all of this.

It isn't required, but you should make sure your immunizations are up to date. There are several that are strongly recommended for travel to China. Your health insurance may not cover the cost of this and your primary care provider may not be able to schedule something quick enough for a business trip. I've used passporthealth for immunizations in situations like this. I've never been asked for my yellow card (shot records) when going through customs but I keep it with my passport.
