Negotiators from 12 Pacific nations have finished a week of talks without agreement on a regional trade deal.Among the sticking points were issues relating to the automobile sector and access to dairy markets.US trade representative Michael Froman said ministers were more confident than ever that a deal on the proposed Trans-Pacific Partnership was within reach, though the date for the next round of talks has not been set.The TPP would encompass 40% of the world economy.It is expected to support jobs and regional economic growth.So how much of a setback is this break-down for the negotiating countries?Is there hope for getting things back on track in the near future?
