U.S. President Donald Trump said on Monday his historic summit with North Korean leader Kim Jong Un in Singapore could “work out very nicely” as officials from both countries met to narrow differences on how to end a nuclear stand-off on the Korean peninsula.

Kim and Trump arrived in the tropical city-state on Sunday for the first ever face-to-face meeting by leaders of two countries that have been enemies since the 1950-1953 Korean War.
