Aoji-ri Chemical Complex
The Aoji-ri Chemical Complex is a large industrial complex in Haksong-ri, Kyŏnghŭng county, South P'yŏngan province, North Korea, which produces about 51 different products, including methane, ammonia, ammonium bicarbonate, and coal tar derivatives. It also allegedly produces blood agents and vomiting agents, including Adamsite.
The Chosen Synthetic Oil Company opened the complex in 1937, originally to produce synthetic oil from the high-quality bituminous coal mined in the area. After the establishment of North Korea, the company was nationalised.
The facility is served by the Korean State Railway via Hoeam station on the Hoeam Line.
