I wouldn't say China is outlawing dogmeat.
A controversial draft version of Anti Animal Abuse Act purposed earlier this year by some Beijing legal scholars contains clauses banning the consumption of dog meat, but that part is extremely controversial.
People are hoping the draft will be discussed during next years parliamentary session but it will probably take a while before the law is passed and I personally see little chance the said clause on dog meat will survive the process.
You see China is a multi-culture society and most people traditionally eating dog meat are in central and southern China, plus millions of Korean Chinese. The law being purposed by Northerners is a easy target for allegations of cultural imperialism. See the whole Cantonese vs Mandarin debacle in Guangzhou, similar things could well happen if a law banning dog meats are introduced. Even in Northern China, Korean restaurants run by Korean Chinese are seen everywhere and dog meat are usually a specialty of those restaurants. Law banning dog meat could well alienate Korean Chinese as well.
