It is untrue.<p>A businesses in foreign countries CAN sue a national governments if pass protectionist regulations that favor domestic businesses.<p>For example: The US can pass environmental regulations blocking all logging on Federally owned land. They can not pass regulations that only allow US-based companies to log on Federally owned land. If they did, then foreign companies could sue for being excluded.<p>&gt;It&#x27;s impossible to have a rational debate on the subject<p>With all the FUD being spread around, I completely agree.
