The chief executive of Broad Sustainable Building, a Chinese construction firm, plans to build at a two-kilometre high, 636-floor tower.
He revealed his plan in an interview to "The Made-in-China CEO", a Reuters magazine published in June.
Zhang Yue , CEO, Broad Sustainable Building, has been quoted, saying: "One hundred per cent! Some say that it&#39;s sensationalism to construct such a tall building. That&#39;s not so. Land shortages are already a grave problem. There&#39;s also the very serious transportation issue. We must bring cities together and stretch for the sky in order to save cities and save the Earth."
