Housing construction makes up a fourth of China's economy. Chinese government is leery of the huge buildup of debt at housing developer companies in China. Banks are involved with their loans to housing developer companies. Some of these bank loans are nonperforming and this percentage of bad debt is growing. It was always a sense of someday this would stop working. That someday may be today.

Efforts are being made to tighten controls on these companies and their way of doing business- raising cash from presold apartments from millions of householders who have accumulated their savings for a speculative investment in a second or third apartment or fulfilling a dream of first home ownership. For two decades it worked as the Chinese economy with the aid of US and European Union transfer of technology and capital grew rapidly. With the US and European Union changing policies and building new supply chains in the competition with China, and China entering the period of a mature economy with less room for growth as Japan did in the 1990's, this buildup of debt  has ominous overtones. Chinese government is making an effort to regulate the housing sector to reduce any potential damage to the economy. The result could be a repeat of the way the Japanese economy after growing rapidly in the period 1960 -1985 slowed rapidly after 1987.
