[7] On 10 October 1992, the day before the 1992 presidential election, Achidi Achu appeared on Cameroon Radio and Television and addressed the people in French, his second language.

In this address, he accused the opposition, led by Social Democratic Front (SDF) candidate John Fru Ndi, of having a "diabolical plan" (plan diabolique) to prosecute and execute the leading figures of the state, government, and military if it won the election, and he urged the people to reject the opposition in order to avert potential violence and instability.

[3] Following Biya's victory in the 1992 election, Achidi Achu remained Prime Minister until 19 September 1996, when he was replaced by Peter Mafany Musonge.

[3] Achidi Achu was later appointed Chairman of the Board of Directors of the National Investment Corporation (Société nationale des Investissements) on 3 March 2003.

[citation needed] In 2009, Achidi Achu became one of three members of the CPDM North West Section's newly established Council of the Wise, which was intended to formulate strategy and tactics to enable the CPDM to attain dominance in the North West Province, where the opposition Social Democratic Front (SDF) has been traditionally dominant.
