HONG KONG — Prime Minister Shinzo Abe of Japan, the first world leader to meet Donald J. Trump after the election in November, plans to meet with the president in Washington on Friday in the Oval Office. Mr. Abe is then planning to fly to Mr. Trump’s Mar-a-Lago resort in Palm Beach, Fla., to play golf with the president.

Why are they meeting?

Mr. Abe wants to talk to Mr. Trump about trade and economic issues, which have already been the subject of some critical Twitter postings and remarks from the president.

Mr. Abe is also eager to pursue a closer personal relationship with Mr. Trump, with whom he shares some ideological leanings, including a resistance to immigration.
