尼日利亚总统在华盛顿与川普总统谈反恐和经济

U.S. President Donald Trump attempted to reset his relationship with Africa on Monday, as he hosted Nigerian President Muhammadu Buhari.

Buhari is the first sub-Saharan African leader to have a White House summit with Trump, who has been criticized for reportedly making derogatory comments about Africa.

During his public remarks with Buhari, Trump focused mostly on common goals and shared interests, such as fighting terrorism and expanding trade.

"We love helicopters — he loves them more than I do," joked Trump, referring to his administration's decision to approve a $600 million military sales deal to Nigeria.

Buhari thanked Trump for approving the deal, which the administration of former President Barack Obama had suspended over allegations of human rights abuses.

"I worked it out so that now you can buy the helicopters that you want," Trump said, adding, "We make the best military equipment in the world, and our friends can now buy it."

Human rights groups have accused the Nigerian military of torture, rape and extrajudicial killing in its almost decade-long campaign against the Boko Haram extremist group.

Tens of thousands of people have been killed in the insurgency, and hundreds of schoolgirls kidnapped, as the group gained notoriety and spread to neighboring countries, posing one of the most severe threats to West Africa's Sahel region in recent years.
