Officials from both countries sought to narrow differences on how to end a nuclear stand-off on the Korean peninsula as the stage was being set for the first ever meeting between the two leaders in Singapore on Tuesday.
"No one expects anything concrete to come of the meeting ... but if the tone is positive afterwards, it won't be a headwind for stocks," said Ken Polcari, director of the NYSE floor division at O'Neil Securities in New York.
Investors also largely brushed off tensions over the divisive G7 meeting, when Trump threw the allies' efforts to show a united front into disarray after taking aim at Canadian Prime Minister Justin Trudeau and announcing that he was backing out of the joint communique.
"Markets are generally overlooking negative takeaway following this weekend's G-7 meeting," said Peter Cecchini, chief market strategist at Cantor Fitzgerald in New York.
