Neocolonialism, the control of less-developed countries by developed countries through indirect means. The term neocolonialism was first used after World War II to refer to the continuing dependence of former colonies on foreign countries, but its meaning soon broadened to apply, more generally, to places where the power of developed countries was used to produce a colonial-like exploitation

Neocolonialism is a wide concept, if you loan a country money you know they cant payback. Then they pay you in unequal treaties ie: Farm land, mining rights etc cheap. When another country controls your strategic interests they are not yours..
