Most likely not. For example, half of all Samsung phones are now made in Vietnam. China is gradually losing all of Samsung's business. The same will ultimately hold true for Apple. Ten years from now, the only companies that will still be making smartphones in China, will be their domestic brands.
Economists tend to forecast at 30 years by extrapolating the last few years. It is not obvious to me that the chinese economic miracle of the last 20 years, largely fueled by foreign investments (every industry in the world outsourcing to China), and after 2008 by domestic debt, is sustainable and reproducible in the long term.
