Saudi Arabia recently announced a grand plan to invest $1 trillion in the construction of a mega building project called 'The Line'. As the core project of the New Future City (NEOM), this building is designed as two parallel mirrored curtain wall skyscrapers, 170 kilometers long, 200 meters wide, and 500 meters high, spanning various terrains such as coasts, deserts, and mountains. After completion, it will become the world's longest building.

Mirror Line "is a vertical city that can accommodate millions of residents. It adopts a three-dimensional layered design, integrating residential, commercial, and public spaces, with supporting vertical farms, high-altitude sports fields, yacht docks, and high-speed underground transportation systems, without the need for cars throughout the entire process. All energy will be generated by clean electricity such as solar and wind power, and water resources will be recycled to create a zero carbon city.  

This project emphasizes ecological protection and only covers an area of 34 square kilometers, with a large amount of land reserved as a nature reserve. Meanwhile, it is located on an international trade channel and can reach 40% of the world's regions within six hours.

The Saudi government plans to fully launch construction by 2025, with the goal of being completed and put into operation by 2030, and is expected to create 380000 job opportunities. Despite the advanced design concept, issues such as its impact on bird ecology and the feasibility of climate control technology still attract widespread attention. The 'Mirror Line' is seen as an important measure for Saudi Arabia to promote economic transformation and achieve sustainable development, and also provides potential opportunities for China and other countries in the fields of green infrastructure and future urban cooperation.
