Concept:Historical colonial relationships shape current trade flows between developing and developed countries.
Explanation:The inclination of some developing countries to their colonial masters has helped to increase trade volume.
Nigeria, as a developing country, maintains a strong economic relationship with its former colonial power.
This relationship provides an existing framework of trade agreements and cultural links.
It also lowers trade barriers and creates mutual trust between trading partners.
Nigeria therefore exports primary products to developed countries and imports manufactured goods from them.
These long-standing ties keep the volume of trade high between Nigeria and the developed world.
Answer:Colonial association with former colonial masters.
