It’s very early stages. We’ve not heard anything directly back from North Korea but we expect to hear something directly from them,” he said during a visit to Nigeria’s capital, Abuja. He was speaking at the end of a week-long trip to five African countries. Tillerson did not clarify which steps were needed for the talks and declined to comment on potential locations.
