Pakistan is one of few countries that has diplomatic and economic relationships with North Korea, a single party state in which the hereditary rule of the Kim family has become an established institution. The start of relations between the two countries emerged sometime in the 1970s during the democratic prime ministerialship of Prime Minister Zulfikar Ali Bhutto, when he made a state visit to North Korea as part of his foreign policy campaign to strengthen the relations with socialist states. Pakistan has an Embassy in Pyongyang while North Korea maintains an Embassy in Islamabad, a vast Consulate-General in Karachi, and consulates in other cities of Pakistan.
