Muhammadu Buhari and Barack Obama had a meaningful official relationship during their presidencies, which focused primarily on security cooperation (and the fight against Boko Haram), combating corruption, and strengthening democracy. Their last official meeting took place in September 2016.
Buhari visited the White House to meet with Obama, on his first trip to the United States as the elected President of Nigeria. Obama praised Buhari's agenda of fighting Boko Haram and eradicating corruption. The United States pledged support, including military assistance and the sharing of intelligence, although an arms sale to the country was initially prohibited due to human rights concerns.
They held a second meeting on the sidelines of the United Nations General Assembly in New York. Obama praised the progress made in the fight against Boko Haram in the region under Buhari's leadership.
The primary focus was combating the extremist group Boko Haram. The US provided support and training to the Nigerian military.
Obama praised the peaceful conduct of the democratic elections in Nigeria, which led to Buhari's election. Buhari, in turn, thanked the US for the diplomatic pressure it applied, which he said ensured a fair election in the country.
The two leaders discussed ways to address corruption in Nigeria and recover stolen funds.
