Department of Tourism spokesman and Assistant Secretary Benito Bengzon Jr. said the underground estuary made it into the world’s New Seven Wonders of Nature after the validation process conducted by the New7Wonders Foundation last year. The voting was criticized, especially the Philippine voting. Nothing in the New7Wonders voting procedure prohibited repetitive voting, making the results subject to government and tourism industry campaigns to vote often for local sites with the financial incentive of increased tourism. Philippine President Benigno Simeon Aquino III, in his speech during the official proclamation launch of the Puerto Princesa Underground River as one of the 28 finalists, urged the country's 80 million cellphone subscribers to vote PPUR via text.
