R&D efforts are concentrated at the State Academy of Sciences, which runs 40 research institutes, 200 smaller research centers, a scientific equipment factory and six publishing houses. The government considers science and technology to be directly linked to economic development. A five-year scientific plan emphasizing IT, biotechnology, nanotechnology, marine technology, and laser and plasma research was carried out in the early 2000s. A 2010 report by the South Korean Science and Technology Policy Institute identified polymer chemistry, single carbon materials, nanoscience, mathematics, software, nuclear technology and rocketry as potential areas of inter-Korean scientific cooperation. North Korean institutes are strong in these fields of research, although their engineers require additional training and laboratories need equipment upgrades.
