Ricciardone spoke Monday with The STAR at a reception hosted by the Philippine Embassy here to celebrate Independence Day.
The reception was held in advance of June 12 because of scheduling conflicts at the venue, the J.W. Marriott Hotel, a stones throw from the White House.
"I am confident the Filipino people will see it to be a free and fair elections," Ricciardone said.
Ricciardone is returning to his post in Manila on June 28 after a five-month absence.
He was recalled on Jan. 15 to coordinate US efforts to help Iraq in its transition to democracy. His departure sparked speculations Washington wanted to be seen as being neutral in a tight presidential election in the Philippines.
"My work in Iraq is finished and I look forward to returning to the Philippines," he said.
Ricciardone said he was eager to be back in Manila in time for the inauguration of the winner of the May 10 elections, expected to be proclaimed by Congress before June 30.
Ricciardone said he plans to remain in the country for at least a year.
But even as Ricciardone prepares for his flight to Manila, his counterpart, Ambassador Alberto del Rosario, is busy winding up his official duties in Washington.
Del Rosario has submitted his resignation to President Arroyo but has been asked to stay on until his successor is named.
