China is building an "artificial sun", a device called HL-2M Tokamak in Chengdu. It is expected to be operational next year as installation work has gone smoothly. 

This "new sun" is able to replicate the natural reactions occurring in the sun and provide clean energy through controlled nuclear fusion. 

The new equipment can generate plasmas hotter than 200 million degrees Celsius, according to Duan Xuru, head of the Southwestern Institute of Physics under the China National Nuclear Corporation.
