Most products are required by law to display the country of origin e.g., “Made in China”. Indeed there phrases have functional uses like calculating export duties, IP protection, anti-dumping etc.

However, they have become a brand by themselves. As with any brand there is a perception & usage e.g., “Made in China” is typically taken to be cheap foreign product & “Made in USA” is often used by people in USA to buy products & support local industries. 

Recently, we have begun to see longer phrases “Designed in California, Made in China”; “Made in China with software from Silicon Valley” etc . This just an attempt at diluting the brand image that “Made in China” brings with it.
