South Korea's unification minister Lee In-young and visiting U.S. Deputy Secretary of State, Stephen Biegun, have been discussing the current situation on the Korean Peninsula.
It's thought they've been talking about the internal stresses and strains within North Korea.
Lee is expected to ask Biegun that the incoming U.S. administration continue to take a leading role in nuclear policies against the regime.
In the coming hours, Biegun will deliver a lecture at a think tank in Seoul.
He's expected to use the opportunity to send a message to the North.
