· TECH Uber’s Efforts to Build Chinese Business Ultimately Fail Against Homegrown Rival Didi So far, no U.S. internet-based company has succeeded in conquering the Chinese market By EVA DOU and KATHY CHU Updated Aug. 1, 2016 10:05 p.m. ET BEIJING—Uber Technologies Co. entered China with billions of dollars to spend and ambitions to dominate the world’s biggest market for ride hailing. It wasn’t enough. After almost three years, Uber agreed to sell its China business to rival Didi Chuxing Technology Co., the Chinese company announced Monday. Despite launching private ride-sharing services in China a full year before Didi, Uber has been outmaneuvered by the homegrown player, which added localized features, landed powerful investors and wooed Chinese regulators and press. Uber and outside investors in Uber China will get 20% in the merged company, which has a combined valuation of $36 billion. U.S. internet companies have long struggled in vain to capitalize on the allure of China’s enormous population and growing wealth. Some have been stymied by strict government licensing and censorship, which contributed to Google Inc.’s decision in 2010 to shutter its China-base search engine and has effectively barred access to Facebook Inc. and Twitter Inc.

Amazon.com Inc. and eBay Inc. both faced off unsuccessfully against Alibaba Group Holding Ltd. “So far we haven’t seen a foreign internet company that has made it big in China,” said Andrew Teoh, managing partner of Ameba Capital, an early investor in Didi. Other companies in the technology industry and beyond have struggled with a range of hurdles in China, including government policies that favor domestic players. Apple Inc. and Microsoft Corp., for instance, have felt a sales chill in China amid Beijing’s growing focus on using “secure” domestic equipment. “The environment has become more challenging,” said Jeremie Waterman, executive director for greater China at the U.S. Chamber of Commerce. “There’s no question that there are Chinese companies that are more competitive than they were five or 10 years ago, but there’s also no question that the government has and is increasingly putting its thumb on the scales to benefit Chinese companies.” China is extremely important to many companies. General Motors Co., which used decades-old alliances in the region to become one of the largest players in the world’s biggest light-vehicle market, counts on Chinese operations for about $2 billion in operating profit annually and has committed to spend 100 billion yuan ($15.1 billion) between now and 2020 on new car development. Although less profitable than U.S. operations, China accounts for about a third of vehicle sales and its position has grown in 2016 as the wider auto market shakes off volatility. Still, a survey released in January by the American Chamber of Commerce in China found that only 64% of .
