President Trump is open to exploring engagement with North Korea under certain conditions, South Korea's foreign ministry said.

Trump told South Korea's presidential envoy of his administration's willingness to try to deal with North Korea through engagement, Reuters reported.

"The fact that Trump said he will not have talks for the sake of talks reiterated our joint stance that we are open to dialogue but the right situation must be formed," said Foreign Ministry spokesman Cho June-hyuck in a regular media briefing, according to the news service.

Earlier this week, Ambassador to the United Nations Nikki Haley warned the U.S. could look to broaden sanctions to include countries that give aid to North Korea.
