Abubakar gave this assurance on Wednesday during a meeting with Igbo leaders in Enugu.
The former Vice President said that he was worried about developments in the country as well as the future of the nation and the legacies that would be left for generations unborn.
“My commitment is to fix this country. I think of the future this country will have, if I do not struggle to fix it.
“Our economy must be fixed and you can trust me and Mr Peter Obi to do it,” he said.
The presidential candidate said that he was equally disturbed about the state of infrastructure in the South East, especially the condition of the Akanu Ibiam International Airport in Enugu.
“I am always scared coming to Enugu because of the state of the runway of the airport. What does it take to fix the runway? A local government council can fix it if they are made viable,” he said.
Abubakar said that the issue of restructuring the country was already settled, adding that he would not be talking about it.
“I am a product of a restructured Nigeria. So it is a settled issue,” he said.
The former vice president said that the comments by some chieftains of the All Progressives Congress (APC) in favour of restructuring and state police were belated and deceitful.
“Article 7 (2) of the Constitution of the APC says that the party believes in restructuring and state police but what have they done about this?
“We need to mobilise ourselves and vote for a ticket that will restructure Nigeria,” he said.
