16. Zimbabwe
Sharing the same score in 150th rank with Cambodia and Burundi is Zimbabwe. This country is stuck with 21 score since 2013.
It is because corruption in Zimbabwe has become an endemic problem. How endemic? The country lost $5 million per day due to corruption.
Corruption is commonly found not just in its political sector, but also private and civil sectors. A survey shows that the police of Zimbabwe are the most corrupt.
Diamond trading is one of the biggest corruption sectors in this country. The national treasure has been smuggled for personal benefits of its leader. How did they do that? They assigned military transport.
