Japan and the United States are working on a trade deal involving agriculture and autos that could be agreed to by Prime Minister Shinzo Abe and President Donald Trump when they meet in New York in September, three industry sources familiar with the discussions said Tuesday.

An auto industry official said the deal could involve Japan offering U.S. farmers new access to its market in return for Washington reducing tariffs on certain Japanese auto parts. But he emphasized the talks remain fluid.

Such a deal would give Abe a win on autos, while helping Trump shore up support among farmers, an important constituency ahead of the 2020 presidential election.
