Ridesharing services are big in China, but they've run into many of the same regulatory concerns you see everywhere else -- officials are worried about holding drivers accountable for their behavior. Accordingly, the country's Ministry of Transport has posted draft rules that toughen the requirements for these app-based transportation outfits. Companies will need insurance and special licenses to operate, and drivers will both need to commit to only one service and maintain a certain level of experience. Data has to be stored within China and shared with authorities, too. Vehicles will also have to seat seven people or less, so you won't be hailing a party bus or stretch limo. The rules could change (they're open to public feedback), but it won't be surprising if these core principles remain in the final document.
