Officials from Japan and the United States resumed a series of meetings Monday to discuss tariffs on agriculture produce under the Trans-Pacific Partnership trade pact, as well as the bilateral trade of cars.

The Japanese and U.S. officials followed up a meeting of chief negotiators with the 12-country TPP initiative, which ended Saturday in Ottawa without any breakthroughs on the current impasse.

Hiroshi Oe, Japan's deputy chief TPP negotiator, and Wendy Cutler, acting deputy U.S. trade representative, began a two-day meeting Monday on the long-standing issue of Japan's demands to maintain exceptional tariffs on some of its farm products under the deal.
