North Korea did not immediately react to the announcement. But South Korea sought to play down concerns.
South Korean Foreign Minister Kang Kyung-wha spoke to Pompeo by telephone Saturday and expressed regret over the cancellation of the trip while calling for continued talks on peace and North Korea’s nuclear program, according to the ministry.
“Rather than reading into each and every turn in the situation, it is more important to focus diplomatic efforts on the faithful execution of what has been agreed in the United States-North Korea summit and the inter-Korean summit, while maintaining the momentum for talks on the long-term outlook,” the ministry said in a statement.
Japanese Foreign Minister Taro Kono expressed appreciation for Pompeo’s “prompt communication” of the decision by telephone and said the two countries would continue to work together to take “specific actions” to achieve the denuclearization of the Korean Peninsula.
From China, though, there was pushback. In a statement released Saturday, Foreign Ministry spokesman Lu Kang blasted Trump for his remarks, saying they showed a "total disregard of the facts."
"China's position on the Korean Peninsula nuclear issue is consistent and clear," the statement said. "We are committed to achieving denuclearization on the Korean peninsula." Kang said China is making "unremitting efforts" to abide by the U.N. Security Council's resolutions, and urged all parties to "stick to the direction of seeking a political settlement."
In tweets, Trump argued that because of his “tougher Trading stance,” the Chinese were not “helping with the process of denuclearization as they once were.”
“Secretary Pompeo looks forward to going to North Korea in the near future, most likely after our Trading relationship with China is resolved,” Trump tweeted. “In the meantime I would like to send my warmest regards and respect to Chairman Kim. I look forward to seeing him soon!”
Experts have said that China continues to broadly enact U.N. Security Council sanctions against North Korea but has eased up on enforcement at the border in recent months. China also has been allowing more Chinese tourists to visit North Korea this year, as relations between the two countries have improved significantly.
But Chung Min Lee, a senior fellow at the Carnegie Endowment for International Peace in Washington, said that China is not responsible for the impasse between the United States and North Korea. Trump “overplayed the gains” from his Singapore summit with North Korean leader Kim Jong Un and needed someone else to blame, Lee said.
Only now does Trump realize that North Korea did not intend to give up its nuclear weapons, at least not as soon as he wanted, Lee said.
Trump is, however, right in one sense, experts said. His trade war with China has caused considerable anger in Beijing and makes it unlikely that the government there could be persuaded to cooperate if the United States wants to return to exerting “maximum pressure” on North Korea’s economy.
“It’s difficult, what Trump is trying to do,” Lee said. “He is trying to punish China on trade . . . At the same time, he wants China’s help.”
Cheong Seong-chang, a North Korea expert at the Sejong Institute, a government-affiliated think tank in Seoul, said Trump has the will to resolve the North Korea situation but lacks a coherent strategy.
“On his last visit to Pyongyang, Pompeo reportedly demanded a list of nuclear sites in North Korea without suggesting any plans for compensation in return,” Cheong said. “North Korea is aware that the list reveals all their cards to the U.S., and they won’t do so without any tangible promise from Washington. The demand for the timeline of denuclearization must come with the timeline for rewards.”
Cheong said the cancellation of Pompeo’s visit put the ball in the court of South Korean President Moon Jae-in, who is due to visit Pyongyang in September and could play a role in facilitating negotiations between Washington and Pyongyang.
But it could also strengthen China’s hand, with President Xi Jinping widely expected to attend Pyongyang’s Sept. 9 celebrations of the 70th anniversary of the founding of North Korea.
“If Xi can produce a meaningful agreement with Kim Jong Un on his September visit to Pyongyang, China will get a boost in the diplomacy game by taking on the role the U.S. failed to play,” Cheong said.
Park Jie-won, a former special envoy of former South Korean president Kim Dae-jung who has met North Korean leader Kim Jong Un and his late father, Kim Jong Il, also warned Trump not to walk away from dialogue.
“If this chance is missed, the future of North Korea will darken towards immense chaos. The leaders of North Korea and the U.S. should go back to Sentosa, Singapore,” he posted on his Facebook page Saturday.
