They have a plan for that...global domination.....where workers and resources flow to China just as they did to Rome.
The middle income trap refers to domestic economic issues, so you are off topic. China is not looking to recreate Rome, because that is not a big thing to them. They certainly do not want an influx of foreign workers. They want to recreate China for obvious reasons. From nearly the beginning of history to 1890, China was the strongest manufacturing country on Earth. There was a tributary system in place for China.
But that is off topic. China has hit the middle income trap, without eliminating extreme poverty, and having already maxed out population growth. That is not a good thing, for China.
By the way RACIST.....whats wrong with Nigeria?
