On Monday, negotiators from the United States and eleven other nations finalized the TPP free trade deal.
"What I know about it [TPP], as of today, I am not in favor of what I have learned about it," Clinton said, when asked if she supports the deal during an interview with PBS released on Wednesday.
Clinton expressed concern about currency manipulation issue, which is not clearly outlined in the agreement. She also said that pharmaceutical companies would ultimately benefit the most from the deal, and as a whole that there were still a lot of "unanswered questions" around the TPP.
"I have said from the very beginning that we had to have a trade agreement that would create good American jobs, raise wages and advance our national security," Clinton said. "And I still believe that’s the high bar we have to meet."
The US Congress still has to vote on the agreement in order or approve or reject it, the vote is expected by early 2016.
If implemented, the TPP agreement would open tariff free trade between the United States, Australia, Brunei, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore, and Vietnam.
The trade talks have been ongoing for six years without public oversight, and the details of the trade deal have not been made public.
