"Legitimacy in my country now comes from the ballot," Ghani said Sunday at the Munich Security Conference.
Ghani stressed that the people of Afghanistan now want to have sustainable peace, enabling them and their children to leave normal lives.
"Peace in the world firmly anchored in our great civilization and commitment to progress," Ghani said.
According to Ghani, the country's security has been beefed up. The president also urged to fight against the Islamic State, al-Qaeda and other extremists.
The results for Afghanistan's presidential elections, held last June, showed that Ashraf Ghani had garnered 56 percent of the votes. His contender Abdullah Abdullah labelled the elections as fraudulent. The candidates agreed to an audit of the ballot.
In autumn, the two candidates signed a power-sharing agreement, following weeks of negotiations. According to the deal, Ghani became president, while Abdullah occupied the new position of chief executive.
