I would urge you to read up on the Chinese cryptography law [1] which took effect on the 1st of this year. Essentially all companies foreign or not must provide unencrypted access to data to the Chinese government and must do so in secrecy. Prior to this, companies were being compelled to give up their data anyways but this just makes things easier.
By the way, the source below is an official Chinese government media source.
