Normally I would say you won't have nexus in any states because you're not shipping the products from the U.S.. However...
I get the sense you're trying to avoid having to register as a company in China which can be nasty. If laws are similar in China to most other parts of the world, this is probably an issue as you're likely a Chinese company (that's something you'd definitely want to seek a lawyer on though). But given that you're trying to disguise yourself as a U.S. company I would suspect this likely means that you're going to end up giving yourself a presence in Delaware and be responsible for remitting tax there.
One way or the other, your predicament is coming because you're trying to have your cake and eat it too :) You're either a Chinese company and you don't have to collect sales tax, or you're a U.S. company and you have to collect sales tax.
You're getting into ever grey areas, so you really want to take to a professional, but hopefully that gives you some room to start.
