China's loss in India could be Elon Musk's gain.

Tesla has had a red-carpet welcome from India for its proposal to invest in the country, while its largest rival in electric vehicles, China's BYD, has been stopped cold by increased scrutiny from New Delhi.

The result could be an opening for Tesla to negotiate terms for an entry to the world's third-largest auto market without the competitive threat from BYD that it faces in other emerging markets, like Thailand.
