What is the Difference between a china made Android phone and a Europe made?

Okay guys i was just wondering what will be the difference between a china made Lenovo android and a europe made lenovo android mobile?
I'm trying to buy it from that online china site called Aliexpress
So, can anybody give me the reasons why i should not or should buy china made/version of lenovo android mobile? Is it really bad? Because they are very cheap comparing to europe and other country made lenovo's

A china made has 3 degrees of quality. They export different qualities to different regions and places.

Ali Express is known for low quality, cheap merchandise.
