Cameroon is viewed as rife with corruption at all levels of government. In 1997, Cameroon established anti-corruption bureaus in 29 ministries, but only 25% became operational, and in 2012, Transparency International placed Cameroon at number 144 on a list of 176 countries ranked from least to most corrupt. On 18 January 2006, Biya initiated an anti-corruption drive under the direction of the National Anti-Corruption Observatory. There are several high corruption risk areas in Cameroon, for instance, customs, public health sector and public procurement. However, the corruption has gotten worse, regardless of the existing anti-corruption bureaus, as Transparency International ranked Cameroon 152 on a list of 180 countries in 2018.
