Adidas, Louis Vuitton, and L'Oreal just plunged after the fall in the yuan - a warning about just how heavily big brands rely on China

L'Oreal has had a factory in Suzhou for the past 10 years, and with that looked to provide employment to those with disabilities in the area. According to the Financial Times, the head of L'Oreal last month said that its Chinese business was booming, saying "We've doubled the size of our business in China over the past four years, and the beauty market there is still very dynamic, especially the luxury segment,"

AB InBev, the world's largest brewer last month scrapped plans to sell $9.8 billion worth of shares in its Asian business, in which was touted to be the world's biggest IPO. AB InBev had been looking to sell a minority sake in it's Budweiser APAC, which markets 50 brands including Budweiser and Stella Artois in China.

Louis Vuitton had found China to be a haven of recent, as the popularity of luxury brands grows in the region. In 2018, China's luxury goods market grew for a second straight year of +20%.

Adidas earlier this year unveiled a new Asia-Pacific and China headquarters in Shanghai and said it plans to open open 1,000 new retail outlets by the end of this year and gear up its digital growth momentum in the country.
