China has built whole cities that nobody lives in! The construction got paid – by government corruption.
They need worker. So send them all the immigrants Europe does not want. Put the to safe, paid work. It will in time earn money, but initially it will fill the empty cities.
They can grow food, and cultivate animals on the surrounding empty fields. It is a win-win situation. The communities are educated and clothed – they just want safe accommodation and jobs.
China has the empty buildings, just going to waste.
