Tesla Soars on Tentative Approval for Driving System in China

Elon Musk’s quick visit to China paid immediate dividends, with Tesla Inc. receiving in-principle approval from government officials to deploy its driver-assistance system in the world’s biggest auto market.

The US carmaker was granted the approval under certain conditions, according to a person with knowledge of the matter, who asked not to be identified because details of all the criteria aren’t clear. Tesla did manage to clear two of the most important hurdles: reaching a mapping and navigation deal with Chinese tech giant Baidu Inc., and meeting requirements for how it handles data-security and privacy issues.
