One example is what you seem to refer to; a solar panel reading made in Vietnam - assembled in Vietnam but by a Chinese owned company with all Chinese components.

Another example is the iPhone reading made in China with a dollar value of 400 but the true value add in China is much lower as all the IP, profit margins, and high value components belong somewhere else.

This means that even though these numbers look very unbalanced it is still Western companies that make biggest part of the profit. (At least so far though things are clearly changing with Chinese companies are climbing up the value chain.)
