The chief negotiators of the 11 remaining Trans-Pacific Partnership countries worked Thursday to narrow down proposed freezes to parts of the original accord following the U.S. withdrawal from the free trade deal.

The 11 countries are seeking to reach a new agreement by November to implement the pact but member countries have made dozens of proposals for freezes to the current deal, in particular clauses introduced at U.S. request.

Japan is seeking to make minimal changes to the current agreement, in the hope that the United States may eventually return to the TPP, Japanese sources said.
