The chips are finally hitting the fan. China has put the word out there that it may play a big power card in the near future: give us all the secrets to your tech, or we won't let you build and sell in our ever-growing Chinese market.
According to the Wall Street Journal, executives have been given a proposal that would provide China with a majority share in any joint venture involving foreign companies introducing "key new-energy components...such as advanced lithium-ion batteries and high-power electric motors". This would allow China to gain control of the technology that minority shareholders (i.e. anyone else) bring to the table.
