The National Emblem of the Democratic People's Republic of Korea is the coat of arms of North Korea, officially known as the Democratic People's Republic of Korea.
 The current version adopted in 1993 is based on a design that was used since the foundation of the republic in 1948.
 Two previous versions were briefly in use in the late 1940s.
 Prominent features on the emblem are a red star, a hydroelectric plant (the Sup'ung dam) and Mount Paektu.
 The design bears similarities to the emblem of the Soviet Union and other emblems of the socialist heraldic style.
Ima Korean is a parody of The Black Eyed Peas' "I Gotta Feeling" by American comedy rapper Rucka Rucka Ali.
 The song was released on February 20, 2010 as a single to iTunes.
 It makes fun of then-North Korean leader Kim Jong-il as well as the culture and stereotypes associated with his country and the wider East Asia.
 The song's cover claimed that it featured Asian-American DJ Not Nice, which is an alias of Ali's.
Diplomatic relations between the Democratic People's Republic of Korea (North Korea) and the Union of Soviet Socialist Republics (the predecessor state to the Russian Federation) were first established on October 12, 1948 shortly after the Democratic People's Republic of Korea was proclaimed.

 The relationship gained some importance again after Kim Jong-Un accepted an invitation to visit Russia (2014–15).
Democratic People's Republic of Korea passports may be issued to citizens of the Democratic People’s Republic of Korea, commonly known as North Korea, for international travel.

The Workers' Party of Korea (WPK) is the founding and ruling political party of the Democratic People's Republic of Korea (North Korea), and the largest party represented in the Supreme People's Assembly.
 The WPK is the sole governing party of North Korea, although it coexists "de jure" with two other legal parties making up the Democratic Front for the Reunification of the Fatherland.
 It was founded in 1949 with the merger of the Workers' Party of North Korea and the Workers' Party of South Korea.
 The WPK also controls the world's 5th largest armed force – Korean People's Army.
 This political party (and all of the other parties in the DPRK) remains illegal in South Korea (officially the Republic of Korea) under South Korea's own National Security Act and is sanctioned by Australia, the European Union, the United Nations and the United States.
The Democratic People's Republic of Korea national basketball team (recognized as DPR Korea by FIBA and known colloquially and in the media as North Korea) represents the Democratic People's Republic of Korea in international basketball and is controlled by the Amateur Basketball Association of DPR of Korea, the governing body for basketball in North Korea.
The Socialist Constitution of the Democratic People's Republic of Korea is the constitution of North Korea (officially Democratic People's Republic of Korea, DPRK).
 It states that the country is socialist and lays out the framework of the national government and the functions of the ruling state party, the Workers' Party of Korea (WPK) in relation to the Cabinet and Supreme People's Assembly (SPA, the country's parliament).
 The constitution is divided into 166 articles, split between three sections.
Kim Wan-su (born 10 May 1939) is the Vice Chairman of the Supreme People’s Assembly (SPA) of the Democratic People's Republic of Korea (DPRK, North Korea).

 He was also the deputy finance minister and became the president of the Central Bank of the DPRK in October 2004 when former President Jong Song-thaek (정성택) was dismissed (according to Radio Pyongyang).
