The US has extended its sanctions against North Korea for a year due to the nuclear threat. This was reported on the website of the White House.
The report notes that the actions of the North Korean government "represent an extreme threat to the national security, foreign policy and economy of the United States."
In early June, US Secretary of State Mike Pompeo said that sanctions against the DPRK would be lifted only if the Korean Peninsula was completely denuclearized.
On June 12, Trump and Kim Jong-un met in Singapore. It was the first ever meeting of acting leaders of countries. They signed a document obliging the DPRK to complete the process of nuclear disarmament, and the United States to guarantee Pyongyang's security.
