U.S. President Donald Trump confirmed Wednesday his CIA Director Mike Pompeo held a secret meeting in Pyongyang with North Korean leader Kim Jong Un.
"Meeting went very smoothly and a good relationship was formed," Trump said on Twitter. "Details of Summit are being worked out now. Denuclearization will be a great thing for World, but also for North Korea!"
Trump had said Tuesday the United States and North Korea "had talks at the highest level" without giving specifics.
Japanese Prime Minister Shinzo Abe, who is visiting Trump at his Florida resort, praised the president Tuesday for agreeing to hold a summit with Kim, saying the move took "courage."
Trump stated "that will be taking place probably in early June or a little before that, assuming things go well. It's possible things won't go well, and we won't have the meetings, and we'll just continue to go along this very strong path that we've taken."
Shortly after, in an extended bilateral meeting with Abe, Trump revealed that in preparation for the summit "we have also started talking directly to North Korea. We have had direct talks at extremely high levels." But that response did not mention Kim by name.
Trump also said Seoul has his blessing to try to negotiate with Pyongyang an end to the 1950s Korean War.
"They do have my blessing to end the war," Trump told reporters as he sat next to Abe at the start of their meeting on Tuesday. "People don't realize the Korean War has not ended," explained Trump. "It's going on right now. And they are discussing an end to the war."
South Korean President Moon Jae-in and North Korean leader Kim are scheduled to hold a summit April 27. A senior South Korean presidential official said Wednesday the peace talks are a possible subject, but that the discussion of formally ending the war would need to involve the other relevant parties.
Active combat in the war ended in 1953 with an armistice signed by the United States (which commanded the United Nations forces), North Korea and China. South Korea was not a signatory, and the two Koreas have never established diplomatic relations.
Abe expressed relief that Trump pledged to address with Kim issues of concern to Tokyo, including abductions of Japanese citizens over decades. He praised the U.S. president for maintaining a tough stance toward Pyongyang's nuclear weapons and ballistic missile programs.
"Donald, you demonstrated your unwavering determination in addressing the challenge of North Korea," the Japanese prime minister told Trump.
According to Larry Kudlow, assistant to the U.S. president for economic policy, "a lot of key issues are on the line" during the two days of talks between Trump and Abe.
The discussions Tuesday at Trump's Mar-a-Lago resort off Florida's Atlantic coast focused on North Korea and turn to trade issues Wednesday, according to White House officials.
"We're certainly going to be taking into account the full range of threats North Korea poses to regional security," said Matt Pottinger, senior director for Asian affairs on the National Security Council.
Japanese officials also want to avoid having Trump try to link any trade negotiations to security matters, a separation strictly maintained during decades of post-World War II diplomacy between the former enemies. But Trump has frequently stated that military allies, such as Japan and South Korea, should pay more for American forces defending them.
"I don't think Prime Minister Abe will leave Mar-a-Lago with anything other than a high degree of confidence in the alliance," predicted Pottinger.
There is disappointment in Japan that despite the close relationship between Trump and Abe, the U.S. government has not exempted Tokyo from tariffs placed on steel and aluminum imports.
"It will be under discussion," Kudlow told reporters. "It's a key point on the agenda."
On a related topic, "the United States would probably like to see a free trade agreement (with Japan) come out at some point," Kudlow told reporters early Tuesday afternoon just hours before Trump and Abe met.
The economic adviser also said that "there's nothing at all concrete" yet on the United States returning to what was the 12-nation Trans-Pacific Partnership.
"It will come up in the summit, no question about it," added Kudlow, in reference to the TPP from which Trump withdrew shortly after becoming president.
Trump has opposed the TPP and reiterated that stance in a tweet late Tuesday.
"While Japan and South Korea would like us to go back into TPP, I don’t like the deal for the United States. Too many contingencies and no way to get out if it doesn’t work," Trump said. "Bilateral deals are far more efficient, profitable and better for OUR workers. Look how bad WTO is to U.S."
Japan is one of the countries that agreed to join the trade pact, but South Korea is not.
