Shanghai has emerged as the front-runner to become the production base for Tesla Motors Inc. in China in an investment that may be valued at about $9 billion, according to a person with knowledge of the matter. Jinqiao Group , a Shanghai government-owned company, has signed a non-binding memorandum of understanding with Tesla on building its production facilities in the municipality, said the person, who asked not to be identified because the negotiations are private.Shanghai Jinqiao Export Processing Zone Development Co., a publicly traded unit of Jinqiao Group, said its controlling shareholder hasn’t signed any documents related to a joint venture for a Tesla Motors Inc. factory.Each party may invest about 30 billion yuan ($4.5 billion) in the partnership, with Jinqiao putting up land for most of its share, according to the person. Suzhou and Hefei are among the cities that are actively seeking to win the investment from Tesla, the person said.At $9 billion, the investment would be larger than Walt Disney Co.’s $5.5 billion Shanghai theme park, which opened this month to fireworks and messages of support from Presidents Xi Jinping and Barack Obama.Jinqiao Export Processing surged by the daily 10 percent limit before trading was suspended. Tesla’s shares closed 2 percent higher at $219.70 on Monday in U.S. trading.“This would be a major win for Tesla and Shanghai,” said Steve Man, an auto analyst at Bloomberg Intelligence. “The investment will probably include a nationwide dealership network, superchargers, R&D center and potentially a second ‘Gigafactory.”’Manufacturing in China would allow Palo Alto, California-based Tesla to avoid a 25 percent import levy, making its electric vehicles more competitive against luxury-brand rivals, such as BMW and Audi, as well as local offerings by BYD Co. and BAIC Motor Corp. Besides its role as a financial center and sea port, Shanghai is also one of the major auto manufacturing hubs in China and home to SAIC Motor Corp., which has joint ventures with General Motors Co. and Volkswagen AG.Foreign automakers that want to set up manufacturing plants in China have to do so through joint ventures in which they can own up to a 50 percent stake. Different provinces and cities compete for the investments, which create jobs and spurs the local economy. Ford Motor Co. has partnered with Changan Group in the southwestern municipality of Chongqing, Hyundai Motor Co. is working with BAIC Group in Beijing, while Nissan Motor Co.’s China venture is based in Wuhan in central Hubei province.Jinqiao Group “has to date not signed any MOU or documents with any individuals on a Tesla joint venture factory,” Jinqiao Export Processing said in a statement to the Shanghai Stock Exchange. Calls to Jinqiao Group weren’t answered, while the Shanghai Jinqiao Economic and Technological Development Zone, a government body overseeing the area, didn’t respond to a faxed request for comment.Khobi Brooklyn, a Tesla spokeswoman, said the company wouldn’t comment on “rumor and speculation.” A spokeswoman for the Shanghai municipal government didn’t confirm or deny the negotiations, saying checks with related parties didn’t yield much clarity.
