Why is China still a 'developing country'?

So why is China still referred to as a "currently developing country"? (1/4 way down ) when they manufacture most of the goods that are purchased in the US? I mean, really, if a country has the infrastructure to produce that much, and the people enough to produce that much, and the infrastructure to keep all those people alive, they're no longer developing.

You can't argue that "the country is so vast that populations/parts don't have running water and electricity. Well, technically you can argue whatever you'd like. But the US has parts where there is no running water, and no electricity.

You can't use Government as a factor. They have one. It's stable. There are many countries that wish they had this.

If it's because parts of their population are uneducated (the same can be said about the US, honestly) - that's by choice of their government. Their government's making fistfulls of money yet they chose to only spend $19/student on textbooks. Does that make them a developing country?

So why is this? Will someone from the lazyweb please explain this to me?
