A Chinese auto glass tycoon has caused a stir by shifting part of his empire to the United States and setting up a factory in Ohio, citing high taxes and soaring labor costs at home. Cao Dewang's USD600-million investment comes after Donald Trump threatened to declare Beijing a currency manipulator and slap 45 percent punitive tariffs on Chinese imports to protect American jobs. The 70-year-old tycoon's decision to open a glass factory in the eastern American state of Ohio in October - a rare case of jobs being exported from China to the US - triggered an outpouring of criticism on social media. The phrase "Cao Dewang has escaped" became a hot topic, generating nearly 10 million views on the Twitter-like Weibo microblog and many comments urging China to "not let Cao Dewang run away". Cao's Fuyao Glass Industry Group claims to be the biggest exporter of auto glass in the world, reporting USD370 million profits last year.
