China is negotiating with the governments of Mongolia, Uzbekistan, Kyrgyzstan and Pakistan to build three connective railroads to improve regional trade on the Silk Road economic belt.

Huang Shengqiang, head of the China Port Management Office, said China has already opened 25 international airports and land ports as well as 12 special trade areas along the economic belt within the country.

It will continue to build regional freight stations and create more trading platforms with Kyrgyzstan, Pakistan, Mongolia and Nepal, Huang said.
