According to the head of state, the problems of poverty, unemployment, lack of adequate medical care are pushing lagging countries to a sense of lack of prospects.
"All this is acutely realized by the lagging countries that are losing faith in the prospect of catching up with the leaders, disappointment spurs aggression, pushes people into the ranks of extremists," Putin said.
He stressed that people in developing countries have a growing sense of unfulfilled expectations, a sense of the absence of any life prospects not only for themselves, but also for their children, which pushes them towards disordered migration.
"This ... in turn creates the preconditions for social discontent in already more prosperous states," Putin added.
Earlier, Putin predicted an aggravation of the food crisis in the world.
