In North Korea, the Constitution provides for "freedom of religious belief"; the Democratic People's Republic of Korea is a secular state. The US and South Korean governments are the main sources of information on religion in North Korea.
North Korea is officially an secular state, and government policy continues to interfere with the individual's ability to choose and to manifest his or her religious belief. The regime continues to repress the religious activities of unauthorized religious groups. Recent refugee, defector, missionary, and nongovernmental organizations (NGO) reports indicate that religious persons engaging in proselytizing in the country, those who have ties to overseas evangelical groups operating across the border in the People's Republic of China, and specifically, those repatriated from China and found to have been in contact with foreigners or missionaries, have been arrested and subjected to harsh penalties. Refugees and defectors continued to allege that they witnessed the arrests and execution of members of underground Christian churches by the regime in prior years. Due to the country's inaccessibility and the inability to gain timely information, the continuation of this activity remains difficult to verify.
Traditionally, religion in North Korea primarily consists of Buddhism and Confucianism and to a lesser extent Korean shamanism and syncretic Chondogyo. Since the arrival of Europeans in the 18th century, there is also a Christian minority. According to the Central Intelligence Agency, since the rise of Stalinism, free religious activities no longer exist as the government sponsors religious groups only to create an illusion of religious freedom. North Korea sees organised religious activity as a potential challenge to the leadership. Religion is practiced privately in secret.
