A government research center, the Korea Computer Center, was set up in 1990, starting the slow development of an information technology industry. In 2013 and 2014, the State Economic Development Administration announced a number of smaller special economic zones covering export handling, mineral processing, high technology, gaming and tourism. The most successful export industry is the garment industry. Production is by a North Korean firm for a European or other foreign partner, by a Chinese firm operating in North Korea with a North Korean partner, or by North Korean workers working in Chinese or other foreign factories. Wages are the lowest in northeastern Asia. The North Korean motor vehicle production establishes military, industrial and construction goals, with private car ownership by citizens remaining on low demand. Having Soviet origins (the subsequent practice of cloning foreign specimens, and a recent automobile joint-venture), North Korea has developed a wide-range automotive industry with production of all types of vehicles. The basis for production is in urban and off-road minis; luxury cars; SUV cars; small, medium, heavy, and super-heavy cargo; construction and off-road trucks; minibuses/minivans, coach buses, civilian and articulated buses, trolleybuses, and trams. However, North Korea produces far fewer vehicles than its production capability due to the ongoing economic crisis. North Korea has not joined or collaborated with the OICA, or with any other automotive organization, so any critical information about its motor vehicle industry is limited. The energy sector is one of the most serious bottlenecks in the North Korean economy. Since 1990, the supply of oil, coal, and electricity declined steadily, and seriously affected all sectors of the economy. Crude oil was formerly imported by pipeline at "friendship prices" from the former Soviet Union or China, but the withdrawal of Russian concessions and the reduction of imports from China brought down annual imports from about in 1988 to less than by 1997. As the imported oil was refined for fuels for transportation and agricultural machinery, a serious cutback in oil imports caused critical problems in transportation and agriculture. According to statistics compiled by the South Korean agency Statistics Korea based on International Energy Agency (IEA) data, per capita electricity consumption fell from its peak in 1990 of 1247 kilowatt hours to a low of 712 kilowatt hours in 2000. It slowly rose since then to 819 kilowatt hours in 2008, a level below that of 1970. North Korea has no coking coal, but has substantial reserves of anthracite in Anju, Aoji (Ŭndŏk), and other areas.
