You're right, most of this is table stakes for production injection molded parts. The part that's particularly relevant for China is that they love to own the tooling themselves. Do not let this happen. Always either own the tooling outright yourself, or do as the article suggests and negotiate a more complicated agreement. The other thing you have to watch out for in China is using low grade steel for molds. That might be a perfectly appropriate move... so long as it's what you are expecting (and paying for). Not so great if you paid for the best and got pot metal! Both problems exist everywhere but are particularly important to watch for in China. The best shops will never do either, but it's still better to cut off these entire classes of problem by being proactive.
