Relations between North Korea and the United States have been historically hostile. The two countries have no formal diplomatic relations. Instead, they have adopted an indirect diplomatic arrangement using neutral intermediaries. The Swedish Embassy in Pyongyang is the US protecting power and provides limited consular services to U.S. citizens. North Korea, officially the Democratic People's Republic of Korea (DPRK), does not have an embassy in Washington, DC, but is represented in the United States through its mission to the United Nations in New York City which serves as North Korea's de facto embassy.

North Korea has a military nuclear weapons program and, as of 2024, is estimated to have an arsenal of approximately 50 nuclear weapons and sufficient production of fissile material for six to seven nuclear weapons per year. North Korea has also stockpiled a significant quantity of chemical and biological weapons. In 2003, North Korea withdrew from the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). Since 2006, the country has conducted six nuclear tests at increasing levels of expertise, prompting the imposition of sanctions.
