"The Trans-Pacific Partnership (TPP) is a proposed regional free trade agreement (FTA) being negotiated among the United States, Australia, Brunei, Canada, Chile, Malaysia, Mexico, New Zealand, Peru, Singapore, and Vietnam. On March 15, 2013, Japanese Prime Minister Shinzo Abe announced that Japan would seek to participate in the TPP negotiations. On April 24, 2013, the Obama Administration gave Congress notice of its intent to negotiate with Japan in the TPP, and Japan is expected to participate in the next round of negotiations in late July 2013. U.S. negotiators and others describe and envision the TPP as a 'comprehensive and high-standard' FTA that aims to liberalize trade in nearly all goods and services and include commitments beyond those currently established in the World Trade Organization (WTO). The broad outline of an agreement was announced on the sidelines of the Asia-Pacific Economic Cooperation (APEC) ministerial in November 2011, in Honolulu, HI. If concluded as envisioned, the TPP potentially could eliminate tariff and non-tariff barriers to trade and investment among the parties and could serve as a template for a future trade pact among APEC members and potentially other countries. Congress has a direct interest in the negotiations, both through influencing U.S. negotiating positions with the executive branch, and by passing legislation to implement any resulting agreement."
