Supposedly, one of his notable contributions to the Philippines was the revival of nationalistic spirit by embarking on a massive promotion campaign for the centennial of Philippine Independence celebrated on June 12, 1998. However, charges of alleged massive corruption or misuse of funds blemished the resulting programs and various projects, one of which was the Centennial Expo and Amphitheater at the former Clark Air Base in Angeles City, supposedly Ramos's pet project. The commemorative projects, particularly those undertaken at Clark, were hounded by illegal electioneering and corruption controversies even years after the Centennial celebrations. Clark Air Base at that point was already completely free of American interference and therefore conceived as a suitable venue for Independence Day. Since in 1992, all American military bases were expelled from the country due to the continuing protests of the Anti-Bases Coalition (ABC), founded by the late Sen. Jose W. Diokno and Sen. Lorenzo M. Tañada.
