Are foreign companies leaving China? Andreas Muller, CEO of Georg Fischer, a Swiss industrial company, said many discuss supply chains on the "talk" level, but there is a need to see what happens on the "walk" level.

In late April, GF held opening ceremonies for its two factories in Yangzhou, Jiangsu province, and Shenyang, Liaoning province. The move showcased GF's commitment to China, which is the biggest single market for all of the company's three divisions.

"We feel very at home in China," Muller said. "The largest number of machine tools are being consumed here in China, so you have to be here in China. The most cars are being built here in China, and the most new electric vehicles are being built in China as well."
