"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. [...] The 16th round of negotiations concluded in Singapore on March 14, 2013, and the 17th round is scheduled to be held in Lima, Peru in May 2013. The current goal is to reach an agreement in time for the October 2013 APEC summit in Indonesia. For this deadline to be achieved, outstanding negotiating positions may need to be tabled soon in order for political decisions to be made. [...] As the negotiations proceed, a number of issues important to Congress are emerging. One is whether the United States can balance its vision of creating a 'comprehensive and high standard' agreement with a large and expanding group of countries, while not insisting on terms that other countries will reject. Another issue is how Congress will consider the TPP, if concluded. The present negotiations are not being conducted under the auspices of formal trade promotion authority (TPA)--the latest TPA expired on July 1, 2007--although the Administration informally is following the procedures of the former TPA. If TPP implementing legislation is brought to Congress, TPA may need to be considered if the legislation is not to be subject to potentially debilitating amendments or rejection. Finally, Congress may seek to weigh in on the addition of new members to the negotiations, before or after the negotiations conclude."
