WSJ: You think North Korea is trying to drive a wedge between the two countries, between you and President Moon? […]

Trump: I will let you know. But if I were them I would try. But the difference is I’m president; other people aren’t. And I know more about wedges than any human being that’s ever lived, but I’ll let you know. But I’ll tell you, you know, when you talk about driving a wedge, we also have a thing called trade. And South Korea — brilliantly makes — we have a trade deficit with South Korea of $31 billion a year. That’s a pretty strong bargaining chip to me.

Trump: I probably have a very good relationship with Kim Jong Un of North Korea. I have relationships with people, I think you people are surprised.

WSJ: Just to be clear, you haven’t spoken to the North Korean leader, I mean when you say a relationship with Korea—

Trump: I don’t want to comment on it — I don’t want to comment, I’m not saying I have or I haven’t. But I just don’t—

WSJ: Some people would see your tweets, which are sometimes combative towards Kim Jong Un…

Trump: Sure, you see that a lot with me and then all of a sudden somebody’s my best friend. I could give you 20 examples. You give me 30. I’m a very flexible person.
