China announced plans in 2017 to establish the Xiongan New Area, located about 100 kilometers southwest of Beijing. The construction is scheduled for this year.

There are two designing plans for the building. One is for the first construction area, or the startup area, designed for taking over Beijing's functions nonessential to its role as the national capital.

The plan for a larger area, about 198 square kilometers, is divided into 12 chapters, including general requirements, functional layout aimed at building a beautiful, natural, ecological environment for Xiongan with a safe and green urban water system, and blueprints for development of high-end and high-tech industries.

It sets a tone of encouraging high-quality shared public services, a green and efficient transportation system, green and intelligent municipal infrastructure, and boast a modern security system.

A 40-member technical team composed of professionals from the Xiongan New Area planning research center and China Academy of Urban Planning & Design is responsible for consulting public opinion on the planning.
