"As we have said for some time, it's really up to the North Koreans to decide when they are ready to engage with us in a sincere way, a meaningful way. They know what has to be on the table for conversations. We've said for some time that I think its important that we have... we are going to need to have some discussions that precede any form of negotiation."

Tillerson said that North Koreans “know what has to be on the table for conversations.” 

As to Vice President Mike Pence’s comments about potentially having talks with North Korea, Tillerson said it’s too early to judge.

On the flight home from his trip to South Korea on Sunday, the U.S. vice president said that the maximum pressure campaign is going to continue unless the North takes steps towards its denuclearlization but added that if the North wants to talk, the U.S. will talk.
