China is overflowing with cheaper, better spec'ed phones than the Moto G. And their own homegrown high end phones that compete for the Iphone end of the market, like e.g. Xiaomi and Huawei phones priced in the same price range as the iPhone.
Xiaomi competes for the consumers who are jealous of the UX of iOS but could not afford a real iPhone. Also Xiaomi fails to match the demands to its flagship products time and time and always runs into shortages.
Yes, India might be a target, though by the time it goes through customs, it won't be $179 anymore. It will be more like $250 - 300. At that price range there are many other good alternatives available here (especially rebranded Chinese ones, that work quite well).
We're comparing entry level but quality phones. 5c is Apple's entry level phone at $549. Moto G is Motorola's at $179. There are lots of cheaper Androids as well as Androids that match the 5c in CPU and screen for less money as well as deals you can get on refurbished/last years phones from both companies, but we're specifically comparing what a new entry level phone is.
