Yes it is OK as China is anyway the main producer of them which then ships them to Europe,US and every other continent.The labor is done mainly in China because there is the biggest technological hub for producing such products,also in Taiwan there are a lot of PCB (Printed Circuit Boards) being produced.

If it is OK to mine or not I don't know as mining is at a big loss right now so it may not be the best moment to start mining but if you are convinced you wanna do it then go ahead and do it.
