Foxconn is Taiwanese not Chinese. Most of their manufacturing is in China so I'm not sure how much that distinction matters in this scenario but I thought it helpful to clarify.

Note that, as far as China is concerned, Taiwan is a part of China. So from their perspective that is even less of a useful distiction.

It's a very useful distinction because de facto Taiwan is not part of China.

tell that to a Taiwanese. They are not going to like you

Most of the IP/software and profit in an iPhone comes from and goes to a US company. Most of the components in an iPhone aren’t from China (nor the USA). Yes, it is assembled in China, but it isn’t accurate to say it is a Chinese product.

There's not much you can do with the IP if China stops being willing to make the product for you. (Unless the IP is so far ahead of the competition you can sell it, but Chinese phone manufacturers are making phones that are very competitive with iPhones.)

Even the Chinese phone manufacturers rely on American software (Android), even if Google gives that away.

If China refused to assemble iPhones for Apple, that assembly could easily be shifted somewhere else: the components are mostly not from China and even the machinery used to assemble the iPhones is mostly German. Apple/Foxconn do it in China because it is the best deal ATM, and shift iPhone assembly around as needed easily (eg iPhones are assembled in Brazil, and will be in India to get around tariffs).

Nokia duh...

HMD it's just sales department slapping Nokia sticker on Foxconn phones
