I'm still confused about the merger between Uber and Didi --- this goes to the completely opposite direction from the traidtional economic notion of fair play and antitrust.
Does China even have antitrust/monopoly laws?
Yep, it's just selective application. If I remember correctly, the last time for an anti-trust case to receive public attention in China was Pepsi v. Huiyuan Juice (Pepsi tried to buy Huiyuan) where the people's court ruled against the merger on ground of antitrust. Funny thing is Pepsi didn't even sell juice products in China. They sold a product called "Cool" (酷儿) which is similar to Snaples --- bottled, flavored juice made from concentrate, far from the traditional notion of orance/apple/peach juice sold by Huiyuan.
