WASHINGTON — President Trump undercut his own Treasury Department on Friday with a sudden announcement that he had rolled back newly imposed North Korea sanctions, appearing to overrule national security experts as a favor to Kim Jong-un, the North Korean leader.
The move, announced on Twitter, was a remarkable display of dissension within the Trump administration. It created confusion at the highest levels of the federal government, just as the president’s aides were seeking to pressure North Korea into returning to negotiations over dismantling its nuclear weapons program.
“It was announced today by the U.S. Treasury that additional large scale Sanctions would be added to those already existing Sanctions on North Korea,” Mr. Trump tweeted. “I have today ordered the withdrawal of those additional Sanctions!”
The Treasury Department announced new sanctions on Friday against Iran and Venezuela, but not North Korea.
However, economic penalties were imposed on Thursday on two Chinese shipping companies suspected of helping North Korea evade international sanctions. Those penalties, announced with news releases and a White House briefing, were the first imposed against North Korea since late last year and came less than a month after a summit meeting between Mr. Trump and Mr. Kim collapsed in Hanoi, Vietnam, without a deal.
It was initially believed that Mr. Trump had confused the day that the North Korea sanctions were announced, and officials said they were caught off guard by the president’s tweet. Asked for clarification, Sarah Huckabee Sanders, the White House press secretary, declined to give specifics.
“President Trump likes Chairman Kim, and he doesn’t think these sanctions will be necessary,” she said.
Then, hours later, an official familiar with Mr. Trump’s thinking said the president was actually referring to additional North Korea sanctions that are under consideration but not yet formally issued.
That statement sought to soften the blow that Mr. Trump’s tweet had dealt to his most loyal aides. Steven Mnuchin, the Treasury secretary, personally signed off on the sanctions that were issued on Thursday and hailed the decision in a statement accompanying them.
“The United States and our like-minded partners remain committed to achieving the final, fully verified denuclearization of North Korea,” Mr. Mnuchin said in the statement. He described the sanctions as part of an international campaign against North Korea that “is crucial to a successful outcome.”
Sanctions are one of America’s most powerful tools for pressuring rogue nations. Mr. Mnuchin has taken great pride in bolstering Treasury’s sanctions capacity and often says that he spends half of his time working on sanctions matters.
Tony Sayegh, a Treasury Department spokesman, referred questions about Friday’s sanctions confusion to the White House.
John R. Bolton, the president’s national security adviser, had also hailed the earlier action against North Korea in a tweet on Thursday: “Everyone should take notice and review their own activities to ensure they are not involved in North Korea’s sanctions evasion.”
Mr. Trump has been eager to strike a deal for North Korea to surrender its nuclear weapons arsenal and, in turn, hand him a signature foreign policy achievement that has eluded his predecessors. Hawks within the administration, such as Mr. Bolton, have been wary of trusting Mr. Kim despite Mr. Trump’s professed strong personal connection to the North Korean leader.
Last month, Mr. Trump was criticized for defending Mr. Kim over the death of Otto Warmbier, an American college student who died in 2017 after being imprisoned in North Korea. Mr. Trump said he believed Mr. Kim’s claim that he was not aware of Mr. Warmbier’s medical condition.
But in recent weeks there have been increasing signs that the thawing relations between the two countries could again turn frosty.
Earlier this month, Vice Foreign Minister Choe Son-hui of North Korea accused Secretary of State Mike Pompeo and Mr. Bolton of creating an “atmosphere of hostility and mistrust” despite the chemistry between Mr. Trump and Mr. Kim.
In another sign of hardening on Friday, North Korea withdrew its staff from the joint liaison office it has operated with South Korea since September. The office was viewed as a potential first step toward the Koreas establishing diplomatic missions in each other’s capitals. But North Korea has expressed frustration with how South Korea has been handling its role as a mediator with the United States.
The talks between Mr. Trump and Mr. Kim broke down because North Korea wanted the United States to roll back some of its most economically painful sanctions without the North immediately dismantling its nuclear program.
As the linchpin of the global financial system, the United States relies on sanctions as one of its most powerful tools for international diplomacy. Officials at the Treasury and State Departments, including career staff members and political appointees, spend months carefully drafting sanctions based on intensive intelligence gathering and legal research.
The North Korea sanctions were no different, and the White House held a formal briefing on Thursday afternoon to explain the rationale behind the actions.
During the briefing, senior administration officials pushed back on the idea that the sanctions sought to increase pressure on North Korea. Instead, they said, the new measures were meant to maintain the strength of existing sanctions.
But one of the senior administration officials strongly rebutted any suggestion that the administration would ease some sanctions as confidence building, or in return for smaller steps by North Korea.
“It would be a mistake to interpret the policy as being one of an it as a step by step approach, where we release some sanctions in return for piecemeal steps toward denuclearization” said the administration official, who spoke to reporters on condition of anonymity. “That is not a winning formula and it is not the president’s strategy.”
While it is not unusual for the White House to have input and even final approval of major sanctions, both Republican and Democratic lawmakers have expressed doubts about Mr. Trump’s ability to execute sanctions policy responsibly.
In 2017, Congress passed legislation imposing sanctions on Russia and limiting the president’s authority to lift them. Under pressure from his own party, Mr. Trump reluctantly signed the bill.
The reversal on the North Korea sanctions drew swift condemnation on Friday from Democrats, who accused the president of being reckless with national security.
“Career experts at the Treasury Department undertake a painstaking process before imposing sanctions,” said Senator Ron Wyden of Oregon, the top Democrat on the Finance Committee. “For Donald Trump to overturn their decision via tweet because he has an inexplicable fondness for one of the world’s most brutal dictators is appalling.”
He added, “Without a well-conceived diplomatic strategy, Trump is simply undermining our national security by making clear that the United States is not a trusted foreign policy partner.”
Mr. Trump’s decision stunned current and former Treasury Department officials, some of whom wondered if the move was planned in advance as a gesture to Mr. Kim. Others feared that America’s vaunted sanctions regime had been compromised.
“For an administration that continues to surprise, this is another first — the president of the United States undercutting his own sanctions agency for imposing sanctions on Chinese actors supporting North Korea,” said John E. Smith, the former director of the Treasury Department’s Office of Foreign Assets Control, who left the department last year. “It’s a win for North Korea and China and a loss for U.S. credibility.”
Sarah Bloom Raskin, who was deputy Treasury secretary under President Barack Obama, said the sudden backtracking on a decision that would normally be made with input from intelligence agencies and the National Security Council was perplexing.
“Reversing sanctions decisions within hours of making the announcement that you would impose them in the first place is a head-spinner,” she said. “This reversal signals the injection of some peripheral consideration or factor that only the president seems to know about and that may have nothing to do with national security.”
The Trump administration did issue some new sanctions on Friday. The Treasury Department announced sanctions against Iran, targeting a research and development unit that it believes could be used to restart Tehran’s nuclear weapons program. It also imposed sanctions on Bandes, Venezuela’s national development bank, and its subsidiaries, as part of its effort to topple the government of President Nicolás Maduro.
