Thursday’s sanctions were intended to send two messages: that the Trump administration will continue to ratchet up economic pressure on Pyongyang until North Korea ends its nuclear and ballistic missile weapons programs, and that the relationship between the United States and Turkey continues to be troubled.

The Trump administration has issued hundreds of similar sanctions this year and is expected to put in place hundreds more. It is unusual for the United States to impose such economic penalties on citizens and companies in allied countries, such as Turkey, which is a NATO member. Even so, the Trump administration has deployed sanctions as one of its most important tools of foreign policy.

Mr. Pompeo is expected to visit Pyongyang this weekend in yet another attempt to get North Korea to begin the process of dismantling its nuclear weapons and missile programs. Last week, Mr. Pompeo told the United Nations Security Council that while negotiations with Pyongyang were going well, sanctions against the country must continue for now.

North Korea responded that the United States is standing in the way of denuclearization. “The U.S. will get nothing from the sanctions, which make its position unfavorable,” the government said in a media statement on Thursday.

Pyongyang has insisted that the United States agree to an end-of-war declaration as a condition for nuclear negotiations to continue. The Trump administration wants North Korea to provide a detailed description of its nuclear and ballistic missile storage and production sites as the first step in a process of unwinding those programs.
