The Error of Fast Tracking the Trans-Pacific Partnership Agreement
National media reported yesterday that a Congressional agreement has been reached on so-called “fast track” authority for the Trans-Pacific Partnership Agreement (TPP). This international agreement, having been negotiated under extreme secrecy by 12 countries including the United States, Australia, Canada, Japan, Malaysia and Singapore, is supposed to be an “ambitious, next-generation, Asia-Pacific trade agreement that reflects…
