Prime Minister Shinzo Abe said he had "very constructive" talks on trade with U.S. President Donald Trump in New York on Sunday, kicking off a busy five-day trip to the United States.

Abe told reporters in New York that they spoke about trade and investment ahead of the second round of their new trade dialogue this week, while also reaffirming their commitment to denuclearize the Korean Peninsula.

The two leaders were to take up the touchy topic of trade again at a meeting scheduled for Wednesday.
