Mining in North Korea is important to the country's economy. North Korea is naturally abundant in metals such as magnesite, zinc, tungsten, and iron; with magnesite resources of 6 billion tonnes, particularly in the North and South Hamgyong Province and Chagang Province. However, often these cannot be mined due to the acute shortage of electricity in the country, as well as the lack of proper tools to mine these materials and an antiquated industrial base. Coal, iron ore, limestone, and magnesite deposits are larger than other mineral commodities. Mining joint ventures with other countries include China, Canada, Egypt, and South Korea.
The Sino-Korean Border Agreement was signed by China and North Korea on October 12, 1962, in Pyongyang. This agreement and a subsequent agreement in 1964 define the modern border between the two countries. The agreement is widely viewed by both modern scholars and by contemporaries as being favorable to North Korea. As a result of the agreement, North Korea acquired 280 km2 of territory on and around Paektu Mountain, and 54.5% of the mountain's Heaven Lake. The previous practice of using the Yalu River and Tumen River for the rest of the border was affirmed.
