The president said this at the presidential villa in Abua while receiving a delegation from King Salman of Saudi Arabia.
Buhari said his administration was mindful of the three-pronged promises made to Nigerians before the 2015 elections.
He said he remained undeterred and focused on securing the lives and properties of all Nigerians.
Buhari told the Saudi Arabian delegation that the priority of his administration had so far been on securing the country, buoying the economy and curbing corruption so that Nigerians would start benefitting from the rich natural and human resources of the country.
The president expressed appreciation to the King Salman Aid and Relief Centre, and the Saudi Development Fund for providing relief materials, worth $10 million, to internally displaced persons (IDPs) in the north-east.
Nasser Bin Mutlaq, leader of the Saudi Arabian delegation said the visit and the donation of materials was an extension of the good relations both countries had shared over the years.
“We are directed to offer materials and food for the displaced persons in the north-east worth 10 million dollars. We have had a field visit to the places and seen the humanitarian situation ourselves,’’ he said.
