A REGULATION, jointly issued by several ministries on Thursday, legalized car-hailing service providers and put forward some fundamental principles for their management. Local governments should now issue detailed regulations for the industry, said Beijing News:

By issuing the regulation, the central government has taken a giant step toward improving and regulating the online car-hailing industry.

Yet the principles of the new regulation must now be fleshed out by local governments, which must draft detailed regulations. That's why the new regulation will come into effect on Nov 1, not now.
