United States Secretary of State Rex Tillerson on Sunday said that Washington is now using "large sticks" instead of a carrot to bring Pyongyang to the table for multilateral negotiations.
"We're not using a carrot to convince them to talk. We're using large sticks. And that is what they need to understand," Tillerson told CBS News's Margaret Brennan in a segment for Sunday's "60 Minutes" program.
He further said that he is "listening" for an indication from North Korea that they are ready for direct talks.
"I am listening. I am not sending a lot of messages back because there's nothing to say to them at this point. So I am listening for you to tell me you are ready to talk," Tillerson said.
The US and North Korea have long been engaged in back-and-forth barbs over the latter's threat of a nuclear attack, however, the Pyongyang participation in the winter Olympics in Seoul raised the speculation of direct talks.
"They will tell me," Tillerson said.
