I'm a little surprised that it is not mentioned in the State Department's advisory, but cybersecurity is one area where you may want to take extra care, especially if you handle trade secrets of any kind. From what I can gather, for the last several years, most savvy MNCs require employees to take "burner" phones and laptops to China that are set up to access everything through a VPN connection, so that no sensitive data is stored on the device itself, and to keep said devices with them at all times and only use their own chargers/dongles. This is of course good practice wherever you go, but there are particularly a lot of stories coming out of business travel to China where people suddenly find weird spyware on their devices etc.
