While the AT822 isn't exactly a world-class microphone, Audio-Technica is very serious about the technical quality of their products. They were making good microphones many years before the Chinese clone factories entered the market and started ripping off the designs (and in many cases, simply copying the spec sheet data even when their products didn't meet those specs) of other manufacturers.
So I'd be very surprised if Nady really offers anything that's the same as what A-T makes. It would defy common-sense economics for a high-quality manufacturer to do all the design and production, only to let themselves be undersold by a lower-prestige competitor. It would be profoundly self-destructive, in fact.
Even AKG, which now has many microphones built for them in Chinese factories, doesn't license their designs to other brands. But you can easily find identical-looking Chinese-made microphones with the same specifications being offered. You need to understand that what you see isn't necessarily what you get.
