After its defeat in World War I, European powers partitioned the Ottoman Empire, annexing some of its territories, and setting up other territories as their "zones of influence". What do the zones of influence mean? Why would they be interested in having zones of influence in the Anatolian lands?
"Zones of influence" were primarily a means of dividing land between two or more colonising nations. This enabled these nations to avoid armed conflict while acquiring more colonies. China and Afghanistan are other examples of lands divided into zones of influence.
Carving a place "Zones of influence" doesn't seem to be that different from colonisation, and probably carried the same benefits that makes colonisation desirable - Access to cheap raw material, market for produced goods, population for military enlisting etc.
