Because our country has a high population density. Why not bring in people from countries with low population density, such as Australia?

Although China has a high population density and many immigrants, Australia and other countries may not necessarily accept immigrants from China. So it's not about exports at all. China can't wait to export more people. China attaches importance to people with special skills and those who have studied abroad. Other countries are not fools, and everyone knows that elites are needed. He doesn't need anyone else, so China can't export its population!
