Trans-Pacific Partnership talks kick off Tuesday in Hawaii, in what could be the final round of negotiations ahead of finalizing a trade-pact.
The chief negotiators are already in Hawaii working on technical issues before the trade ministers arrive this week.
The Trans-Pacific Partnership includes the United States and 11 Pacific Rim countries.
In a report by the Economist, the TPP trade deal is the most important free-trade agreement in years.
If completed, it will be the largest regional trade deal ever, with its members accounting for nearly 40% of the world economy.
The trade talks remain confidential but once complete, governments will have several months to review the final deal.
