WASHINGTON >> President Donald Trump undercut his own Treasury Department today by announcing that he was rolling back North Korea sanctions that it imposed just a day ago.

The move, announced on Twitter, was a remarkable display of dissension within the Trump administration and showed how actively the White House is intervening in policies that are traditionally handled by career officials in the Treasury and State Departments. Trump appeared to confuse the day that the North Korea sanctions were announced, saying that it occurred today rather than Thursday.

“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,” Trump said on Twitter. “I have today ordered the withdrawal of those additional Sanctions!”

On Thursday, the Treasury Department imposed new sanctions on two Chinese shipping companies that it says have been helping the country evade international sanctions. The sanctions linked to North Korea were the first that the Treasury Department had imposed since late last year and came less than a month after a summit between Trump and Kim Jong Un, North Korea’s leader, collapsed in Hanoi, Vietnam, without a deal.

Sarah Huckabee Sanders, the White House press secretary, said the decision was a favor to Kim.

“President Trump likes Chairman Kim, and he doesn’t think these sanctions will be necessary,” she said.

Tony Sayegh, a Treasury Department spokesman, did not immediately respond to a request for comment on Trump’s tweet.

The department did issue a new round of sanctions Thursday on Iran, targeting a research and development unit that it believes could be used to restart Tehran’s nuclear weapons program.
