President Trump will meet with North Korean leader Kim Jong Un by May for high-level talks toward a nuclear-free Korean peninsula, South Korean national security adviser Chung Eui-yong said outside the White House on Thursday. 

It would be the first face-to-face meeting between a U.S. president and a North Korean leader. 

The announcement comes days after North Korea said it was open to talks and offered to suspend nuclear missile and weapons tests during them.

Here are answers to the key questions about the latest development.

Why did Trump accept the offer?

That remains unclear. In the days leading up to Thursday's announcement, the Trump administration said it wanted to see some concrete actions before agreeing to meet with Kim. The administration never made clear what those actions might be, and North Korea hasn't taken any visible steps toward denuclearization in recent days. North Korea has agreed to refrain from testing nuclear weapons or missiles and to accept that the United States and South Korea will conduct regularly scheduled joint military exercises. Those assurances were enough to convince Trump to meet with Kim, the White House said. 

Is North Korea serious about giving up its nuclear arsenal?

Probably not, but if it consents to talks and suspends nuclear tests as promised, it still could result in progress that further defuses tensions.

“It’s not an unconditional commitment to get rid of its nuclear program,” said Robert Einhorn, an arms control analyst at the Brookings Institution. “It’s not clear they’re committing to anything at this point.”

Is there an upside even if North Korea doesn't give up its weapons?

Holding talks, particularly between two leaders who often rely on their instincts, can sometimes yield unanticipated results. “It is a big window of opportunity,” said Jenny Town, assistant director of the U.S.-Korea Institute at Johns Hopkins School of Advanced International Studies. Even if North Korea doesn't agree to dismantle its nuclear arsenal — which the United States has demanded — it could agree to a suspension of future nuclear activity. That, in turn, could lessen tensions and reduce the chances of a mishap that could lead to war. It also might lead to further talks about a comprehensive disarmament.

Should the United States trust North Korea?

There are plenty of reasons to be skeptical. “We shouldn’t be under any illusion that they are going to give up nuclear weapons easily,” Town said.

Previous efforts to contain North Korea's nuclear arsenal, including an agreement in 1994, ended in failure amid strong evidence that North Korea was moving ahead with an enrichment program despite the deal with the United States.

North Korea has also regularly objected to visits from weapons inspectors during previous discussions of disarmament, said Balazs Szalontai, an associate professor at Korea University.
