Update president buhari in malabo for gas summit

I think there may be some confusion here.

President Muhammadu Buhari is the President of Nigeria, not Malabo. Malabo is the capital city of Equatorial Guinea, a country located in Central Africa.

It's possible that you may be referring to the Gas Summit that took place in Malabo, Equatorial Guinea, in 2017. The summit was attended by several African leaders, including President Teodoro Obiang Nguema Mbasogo of Equatorial Guinea, who hosted the event.

However, I couldn't find any information that suggests President Muhammadu Buhari of Nigeria attended the Gas Summit in Malabo, Equatorial Guinea. If you have any further information or context about the summit, I'd be happy to help clarify things for you!
