According to a Wall Street Journal report, global automakers such as General Motors (GM) and Volkswagen (VW) are now running their plants at less than full capacity for the first time, and canceling shifts.

For the past several years, China has been the carrot that everyone in the automotive industry has been reaching for. A rapidly growing population with an even faster growing appetite for luxury goods and automobiles resulted in China surpassing the U.S. in terms of vehicle sales in recent years.

Now, it seems automakers are thinking twice about China’s prospects as the financial markets have tumbled in the past week, taking with it possible future automotive sales. Global vehicle manufacturers have more plants in China than anywhere else in the world, according to the Wall Street Journal (WSJ). However, passenger vehicle sales in China fell two months in a row, in June and July.

According to the WSJ report, global automakers such as General Motors (GM) and Volkswagen (VW) are now running their plants at less than full capacity for the first time, and canceling shifts. China accounts for 35 percent of VW’s global vehicles sales, and 35 percent of GM’s as well, according to the WSJ.

The report also noted that the Chinese government’s crackdown on corruption, restrictions on vehicle ownership to help improve air quality and currency devaluation are all having an impact on slowing vehicle sales.
