This is not going to be popular...

Part of China's grand plan to own the EV space is to force foreign companies to divulge their secrets if you want access to the Chinese market. The manufacturers would be put into a joint venture with a local vendor but the local vendor would have 51% of the company.

While this is not a confirmed plan there is confirmation that the Chinese government is leaning this way. If so, interesting to see if manufacturers will ignore or delay introduction into China (as Toyota has with the Prius). No word on if the WTO will file a complaint against China if they go this route. Rest assure if they do a significant airing of grievances will take place.
