Canada and Mexico have officially been invited to join the Transpacific Partnership Agreement (TPP) negotiations.  U.S. Trade Ambassador Ron Kirk said, “Inviting Canada to join the TPP negotiations presents a unique opportunity for the United States to build upon this already dynamic trading relationship.  Through TPP, we are bringing the relationship with our largest trading partner into the 21st century.”  Secretary of Agriculture Tom Vilsack said, “For decades, two-way agricultural trade between Mexico has created good-paying jobs here in the United States.  Mexico’s participation in TPP will allow U.S. agriculture to leverage existing supply chains, adding to the economic significance of a TPP agreement and ensuring that American agriculture remains a bright spot in our nation’s economy.”  Mexico will now join the negotiations with the United States, Australia, Brunei Darussalam, Chile, Malaysia, New Zealand, Peru, Singapore and Vietnam.
