China Metallurgical News (CMN) office was founded in 1956, affiliated to Ministry of Metallurgical Industry and State Bureau of Metallurgical Industry respectively. In 2001, CMN was subordinated to China Iron and Steel Association. During the past half century, our newspaper has given numerous reports about the policies of the government and the party, advanced technologies, excellent people and management experience of the steel companies, all kinds of information about the steel industry and some related industries. At present, our newspaper has already built an information-exchange platform for the upstream and downstream of the industrial chain, which makes the steel as the key contents. All those devote a lot to the Chinese steel industry, and make us the most authoritative and influential newspaper in the field.
