Lenovo has launched the A7 in China. It is a considerable departure from your average smartphone, in that the processor here is from Unisoc. Not only that, but it has a swappable 4000mAh battery. It does not have a sale price as yet, but is likely to exhibit an ultra-budget one on its announcement.

The article from ITHome in your source says that the phone was launched "outside" of China in its original title. In that article, it says that the phone was launched in Middle East and will be available in Europe and Africa in the future. The article from MySmartPrice might have mis-translated the original text to say that the phone was launched "in" China.
