Pacific Rim officials meet in Hawaii this week for talks that could make or break an ambitious trade deal which aims to boost growth and set common standards across a dozen economies ranging from the United States to Brunei. Trade ministers go into the talks, which run from July 28 to 31 on the island of Maui, with high hopes of a pact to conclude the Trans-Pacific Partnership (TPP), the most sweeping trade deal in a generation and a legacy-defining achievement for U.S. President Barack Obama. But although officials in Maui said the mood was optimistic, the toughest issues have been left until last, including monopoly periods for new life-saving medicines and preferential treatment for state-owned companies, besides more traditional issues such as allowing more competition in protected markets. “This meeting will be extremely important to decide the fate of the TPP negotiations,” Japanese Economy Minister Akira Amari told reporters on Friday. “I believe all the nations will come to the meeting with their strong determination that it has to be the last one.” Canadian Trade Minister Ed Fast was more cautious, warning last week that there was a lot of hard work still to be done. Canada’s refusal so far to accept more dairy imports is a major sticking point in the talks, infuriating the United States as well as New Zealand, which has said it will not sign a deal that fails to open new dairy markets. Mexico, which buys half its imports from Canada and the United States and very few from other TPP countries, was also falling short in opening its markets, a source close to the talks said. Failure to agree this week will endanger an already tight timeline to get a deal through the divided U.S. Congress this year, before the 2016 presidential campaign dominates the agenda. A six-week battle over U.S. legislation to streamline the passage of trade deals through Congress finally ended in late June, sparking a rush of negotiations to ready ministers to take the tough decisions needed to wrap up the talks. Tami Overby, senior vice president for Asia with the U.S. Chamber of Commerce, said it would be very difficult to keep the momentum going if ministers failed to reach agreement this week, although she added that she was optimistic of success. A U.S. official said talks would continue if there was no finalized agreement in Maui. Peruvian unions, however, recently filed a complaint with the U.S. Department of Labor, saying their government was falling short of standards in a 2009 U.S.-Peru trade deal, which, like the TPP, is supposed to ensure internationally-recognized labor benchmarks. Workers’ rights in TPP countries, especially Vietnam, have been a key concern for U.S. Democratic lawmakers, many of whom fear the trade deal will eliminate U.S. jobs partly because of lower labor standards overseas. Some trade diplomats from TPP nations doubted whether ministers could produce a detailed agreement by Friday. One option would be to reach an in-principle deal and then finalize details later, one official said. (Reuters)
