The United States, Australia, Brunei, Chile, Malaysia, New Zealand, Peru, Singapore, Vietnam, Mexico and Canada are all part of the talks. Tokyo is the latest entrant.
Froman reiterated that the United States has parallel negotiations with Japan on a broad range of issues, from autos to agriculture, in a renewed effort to force open markets. The result of those talks will be wrapped into the TPP and will be enforceable.

He said policies that keep out most U.S. auto imports "are not likely to change after decades of the same situation."
"Nothing has ever worked."
