Negotiations started in March 2010.  The original deal was finished in January 2016 with 12 parties.  When the United States withdrew a year later, many people expected the agreement to die a quiet death. However, officials persevered and fought hard to maintain the high quality of the trading arrangements.  For many, this meant accepting tough provisions originally negotiated as part of a comprehensive package with 12 members. The consequences of the final agreement are important for companies.  Our brand-new booklet on 10 Benefits of the CPTPP can be downloaded here.  The final agreement signed in Chile pared back the commitments by suspending 19 elements, amending one provision, and clarifying the terms for two others.  (For more specific details, see our revised Policy Brief 17-11a.)
