"Nigeria prefers to have schoolgirls abducted by Boko Haram from Chibok and Dapchi back alive, and that is why it has chosen negotiation, rather than a military option", a statement issued by the president's spokesman stated.
"We are trying to be careful".
She said they would go there, sit, listen and talk to one another about managing situations as traumatized parents whose daughters were still in Boko Haram's hands. While the group terrifies nearly anyone in their path, members of Boko Haram have taken particular aim at schools due to their belief that western civilization and education should be forbidden.
The President promised that his administration would continue to do its best to secure the country, adding that he would be in Yobe State, from where the Dapchi schoolgirls were abducted, later this week "as part of my condolence and sympathy visits to areas where we have had unfortunate events".
I think this is the best way to help the Nigerian government to get these girls released, which we hope will be done peacefully.
Tillerson said Nigeria was a very important country to the U.S, stressing that "You have our support in your challenges".
Nigeria and the United States of America are set to establish a Commercial and Investment Dialogue as well as a Trade and Investment Framework Council between the two countries as a way of deepening trade and investment opportunities.
On preparations for the 2019 general elections, the president pledged that there will be free and fair polls come next year.
"In my discussion with President Idris Deby in Chad earlier today, we spoke about the threat of Boko Haram and how to deal with the sect's menace".
Buhari explained to Tillerson, how his government plans to negotiate for the release of 110 girls abducted from a school in the northeastern town in February 2018, rather than use a military operation to free them by force.
In his contribution, Nigeria's Minister of Foreign Affairs, Mr Geoffrey Onyeama, said Nigeria had succeeded in degrading Boko Haram, contrary to reports in the social media.
He said, "With regards to the kidnapped girls in Dapchi, it is incorrect to say we took a week to acknowledge".
