Buhari attend eu au summit abidjan

I think there may be a slight mistake. The EU-AU Summit was held in Brussels, Belgium, not Abidjan.

The 5th EU-Africa Summit, also known as the EU-AU Summit, took place on February 17-18, 2022, in Brussels, Belgium. The summit was attended by European Union leaders, including European Commission President Ursula von der Leyen and European Council President Charles Michel, as well as African Union leaders, including African Union Commission Chairperson Moussa Faki Mahamat.

As for President Muhammadu Buhari of Nigeria, he did not attend the EU-AU Summit in Brussels. However, Nigeria is a member of the African Union and has participated in previous EU-AU Summits.

If you have any further questions or clarification regarding the EU-AU Summit or President Buhari's attendance, please feel free to ask!
