TOKYO (Reuters) - Japan and the United States continued the second of two days of tough trade talks on Monday that could pave the way for a broader trans-Pacific agreement, although Tokyo shrugged off expectations of a bilateral deal in time for a summit next week.
Japanese Prime Minister Shinzo Abe, speaking on an evening news program in Tokyo, said negotiators were engaged in "intense" talks but that the discussion had narrowed to a few, lingering items.
Abe likened the talks to mountain climbing, saying there was "one, tough stretch" to complete.
"We would like to redouble our efforts so that a deal can be reached," he said.
Access to Japan's rice market and the U.S. auto parts market remain obstacles to a bilateral deal between the two nations, which is vital to the success of a long-delayed Trans-Pacific Partnership (TPP) pact.
Speaking to reporters ahead of the meeting in Tokyo, Economy Minister Akira Amari said top-level negotiations with U.S. Trade Representative Michael Froman, would be "very tough", adding that bilateral talks would hit the "most critical stage".
The world's biggest and third-biggest economies account for some 80 percent of the economic output of the 12-member TPP.
"I'd like to make utmost efforts to narrow the distance between Japan and the United States, while taking into account national interests," Amari was quoted as saying by public broadcaster NHK.
Amari on Sunday said Japan would not accept a U.S. demand to substantially expand its rice imports, while pressing Washington to further open the U.S. car-parts market.
He reiterated that he did not expect a deal before a summit between President Barack Obama and Prime Minister Shinzo Abe in Washington on April 28, but nonetheless hoped to make progress.
"Because outstanding issues are difficult, we are not expecting all issues will be resolved this time although we want to make meaningful progress that will allow us to see light at the end of the tunnel," said a Japanese government source familiar with the negotiations.
Japan is set to allow a special quota of about 100,000 tonnes a year for rice imports from its 11 TPP partners, the bulk of which is expected to come from the United States, the Nikkei business daily reported on Monday. The United States is demanding roughly double the size of quota, the Nikkei said.
Japan has sought immediate abolition of a 2.5 percent tariff on U.S. imports of auto parts, but Washington, under pressure from the politically powerful auto industry, wants to maintain auto-related tariffs as long as possible, the Nikkei reported.
Prospects for the bilateral deal improved on Thursday, when senior U.S. lawmakers agreed on the wording of a bill to give Congress a yes-or-no vote on TPP but not the power to alter a deal. However, passage of the "fast track" bill, which Japan says is essential, remains far from assured.
Washington and Tokyo see strategic as well as economic value to a broad TPP deal as a counterweight to rising China, which has not joined the group.
