What system promoted economic growth between the colonies and the other nations

I think that recently industrialized countries are countries whose economies have not yet reached the status of those developed, but have advanced, in the macroeconomic sense.

Other characteristics of the recently industrialized countries are their rapid economic growth (usually oriented to the export of goods) and an almost complete or ongoing industrialization process. In many newly industrialized countries, social change can occur in the form of emigration from rural or agricultural-dependent populations to cities, where growth and manufacturing factories attract thousands of workers.
