What’s a Chinese victory? Look up the Opium wars, and China’s usual reaction to problems in what they consider their buffer nations. In other words, shoot everyone involved in the drug trade, from growers to smugglers to dealers to users. Then invade the neighboring country and kill everyone within a few hundred miles of the border. Then go home.
Drug War won, drug problem over. For a generation or two. Repeat as necessary. Bottom line: nobody really cars if you kill criminals and drug addicts by the boatload. And they care even less if you slaughter thousands of turd world peasants.
