HIGHLIGHTS-Key quotes from Reuters interview with Trump

(Adds additional highlights)

WASHINGTON, Jan 17 (Reuters) - Here are highlights of the Reuters Oval Office interview with U.S. President Donald Trump on Wednesday.

ON NORTH KOREA'S KIM JONG UN

"Well, I'd sit down but I'm not sure that sitting down will solve the problem.

"I'm not sure that talks will lead to anything meaningful. They've talked for 25 years and they've taken advantage of our presidents, of our previous presidents."

ON WHETHER HE HAS COMMUNICATED WITH KIM

"No, I just don’t want to say as to whether or not we’ve had communication. But, but we will see how that plays out. OK? And hopefully it can be done in a peaceful way but it’s very possible that it can’t."

ON A PRE-EMPTIVE STRIKE AGAINST NORTH KOREA

"Well, again I don't want to say what options I want to consider. I just don't think we should be talking about options to the media."

ON WHAT HIS REACTION WOULD BE TO NEW NORTH KOREAN ICBM TESTS

"I don't like talking about things like that.

"We're playing a very, very hard game of poker and you don't want to reveal your hand."

ON CHINA, RUSSIA ROLES IN NORTH KOREA ISSUE

"I spoke with President Xi (Jinping) the other day, who I have a great chemistry with, I have a great relationship with.

"They're doing a lot ... But they can do more. Ninety-three percent of the trade goes through China.

"Russia's not helping us at all with North Korea. He (Russian President Vladimir Putin) can do a lot. But unfortunately we don't have a relationship - I think it's too bad, but unfortunately we don't have much of a relationship with Russia, and in some cases it's probable that what China takes back, Russia gives. So the net result is not as good as it could be."

ON WHETHER NORTH KOREA COULD HIT THE U.S. WITH A MISSILE

"I don't think - they're not there yet, but they're close. And they get closer every day. And again, this is a problem that should have been handled over the last 25 years before they were this close or before they did have a capability."

ON MISSILE DEFENSE EXPANSION

"We're ordering more missile defense and we're ordering more missile offense also. We have been very depleted as a nation and I would love to spend money on other things but I'm also a person of great common sense."

ON TIMING OF TRADE ACTIONS

"We’re going to be doing and we’ll announce something.

"I’ll talk about it at the State of the Union (annual address).

"It’s not only China. China’s just the biggest. It’s everybody."

ON SOLAR PANEL TRADE ISSUES

"They dump the panels, then everybody goes out of business. I think I heard we lost like 20 of 22 ... solar panel companies. How many have we lost, Gary?" (Economic adviser Gary Cohn: "We're down to two. And one is basically on the edge of bankruptcy.")
