I don't think I can copy the entire article, but i guess this is interesting :
"China had previously circulated a proposal that would
allow electric-car makers into the country without local partners if they were to locate in the so-called free-trade zones. The government set up the country’s first such zone in Shanghai in 2013, and has since approved 10 more around the country.
Until now, foreign auto makers have built cars in China through joint ventures with local manufacturers. That allows them to avoid the 25% tariff on autos, but also forces them to split profits, and potentially share technology, with the local partner—something that has tripped up Tesla’s previous efforts to expand there.
Under current rules, the cars Tesla builds in the free-trade zone would still count as imports and incur the tariff. Auto analysts in Shanghai doubt the Chinese government has any incentive to give Tesla special treatment.
“Government regulators examine every deal and try not to set a precedent,” said Bill Russo, chief executive of Automobility, a Shanghai-based consultancy, and a former Chrysler executive. “Whatever deal Tesla gets, others will want it too.”
A plant in Shanghai’s free-trade zone still has clear benefits, Mr. Russo said. It would give Tesla a base from which to export to the region, while offering proximity to the Chinese supply chain, thereby lowering production costs and the sale price of Tesla cars sold there. Today, a Tesla costs roughly 50% more in China than it does in the U.S."
