Nonsense. The first three words are important here: "No Party shall...". The Parties to the TPP are the member states, not the persons within those states.

This is entirely about declaring that China can't say "Microsoft can't sell software here unless they give us their source code". (Yes, China isn't part of the TPP. But the TPP is intended to be a model for future trade deals, so there are lots of clauses which have zero effect on the signatories but will affect China.)
