[CA/TW/CO/JP/MX/US propose: No Party may prevent a service supplier of another Party [CO/JP propose: or consumers of those suppliers,] [CA/CO/JP/TW/US propose: from transferring, [accessing, processing or storing] information, including personal information, within or outside the Party’s territory, where such activity is carried out in connection with the conduct of the service supplier’s business

[US propose: Nothing in Section III (Electronic Commerce) shall be construed to prevent any Party from taking any action which it considers necessary for the protection of its own essential security interests .]
