Suga said Trump and Prime Minister Shinzo Abe are considering signing a deal in late September when they attend the U.N. General Assembly in New York. "We are accelerating the work that still remains," he said. "But I decline to comment further because we have not reached a formal agreement."
Trump's notice to Congress, released by the White House on Monday, did not mention tariffs on autos and parts, long a sticking point between the two countries. It said his administration was looking forward to collaborating with lawmakers on a deal that would result in "more fair and reciprocal trade" between the two countries.
Toshimitsu Motegi, who became foreign minister last week after negotiating the deal as economy minister, said Japan must watch carefully to prevent Washington from forcing any last-minute changes, Kyodo News agency reported.
The agricultural minister, Taku Eto, cautioned against letting down Tokyo's guard until the final agreement is reached, it said. A long-sought trade agreement with Japan was scrapped when Trump withdrew the U.S. from a pan-Pacific trade agreement shortly after taking office in 2017.
Japan and the other 10 remaining members of the trade pact, the Trans-Pacific Partnership, then renegotiated their own deal without the U.S. Trump said he preferred that Washington and Tokyo strike a bilateral deal.
That resurrected the longtime issue of tariffs on Japanese car and auto parts exports to the U.S. and of stiffer duties on U.S. exports of farm and other products to Japan.
