President Lee Jae Myung's visit is expected to spotlight trade, alliance costs and North Korea as he seeks to set the tone with Trump's second-term White House.

Korean President Lee Jae Myung arrived in Washington on Sunday afternoon for a three-day trip to the United States to hold a highly anticipated first summit with U.S. President Donald Trump.

At a summit meeting in Washington, D.C. on Monday, the U.S. and South Korean presidents will discuss modernizing their 71-year-old alliance and fleshing out a trade deal reached last month.
