The State Council, the country's cabinet, said it would close outdated plants and refuse to license new steel projects, the official media reported today.
Crude steel production declined 2.3 per cent year-on-year to 803.8 million tonnes in 2015, the National Bureau of Statistics said last month. Xinhua news agency described it as the first drop since 1981.
China accounts for half the world's crude steel production, according to data from the World Steel Association.
Experts say China is sitting on an overproduction of 340 million tonnes.
The current production capacity is 1.2 billion tonnes, but the country only produced 804 million tonnes last year, it said.
European producers accuse Chinese firms of selling below the cost of production, and French economy minister Emmanuel Macron has warned that Europe would not accept the "Chinese dumping".
Steel producers have also been hit by concerns over China's slowing growth, which reached 6.9 percent in 2015, its slowest for 25 years.
Many of China's giant state-owned enterprises are unviable and Premier Li Keqiang has called for a "cutback on overcapacity in traditional industries as well as a large number of zombie enterprises".
