SEOUL, South Korea — Softening his aggressive rhetoric, at least for the moment, President Donald Trump stood on South Korean soil Tuesday and urged North Korea to come to the negotiating table. It’s time, he said, for the North to “make a deal” to rein in its nuclear weapons program.

It was a striking shift in tone for the president, who for months has issued increasingly dire threats to answer any hostile North Korean action with “fire and fury.” On Tuesday, his first day on the Korean Peninsula as president, Trump said he’d seen “a lot of progress” in dealing with Pyongyang, though he stopped short of saying whether he wanted direct diplomatic talks.

“It makes sense for North Korea to come to the table and make a deal that is good for the people of North Korea and for the world,” Trump said at a news conference with South Korean president Moon Jae-in. “I do see certain movement.”

Trump was winding down his visit to Seoul on Wednesday with an address to South Korea’s National Assembly, where he was expected to outline his view of dangers posed by North Korea’s nuclear weapons program. The next stop on his five-nation Asian tour: Beijing, where he will press China to constrict the North’s economic lifeblood.

Ever the showman, Trump teased that he had a surprise in store for today, saying at a Tuesday evening banquet that he had an “exciting day” planned — “for many reasons that people will find out.” He did not elaborate.

Overall, the president sounded an optimistic note on disagreements with the North, saying confidently, if vaguely: “Ultimately, it’ll all work out.” Whether the shift in rhetoric signaled a change in policy or diplomatic strategy remained uncertain.

Mark Fitzpatrick, executive director in Washington for the International Institute for Strategic Studies, said it could simply be Trump projecting “what he most recently heard” from Moon and Japan’s Shinzo Abe.

“I expect he heard from both Prime Minister Abe and President Moon the need to give diplomacy a chance,” Fitzpatrick said. “Of course, it’s not the first time he has talked about engaging with North Korea. The issue has been one of timing. Now is a good time, during a pause in missile testing.”

North Korea has fired off more than a dozen missiles this year but none in nearly two months. But analysts caution against reading too much into the pause.
