The nominal gross domestic product (or GDP) of French Polynesia in 2014 was 5.623 billion U.S. dollars at market local prices, the sixth-largest economy in Oceania after Australia, New Zealand, Hawaii, New Caledonia, and Papua New Guinea. The GDP per capita was $20,098 in 2014 (at market exchange rates, not at PPP), lower than in Hawaii, Australia, New Zealand, and New Caledonia, but higher than all the independent insular states of Oceania. Both per capita and total figures were significantly lower than those recorded before the financial crisis of 2007–08. French Polynesia has a moderately developed economy, which is dependent on imported goods, tourism, and the financial assistance of mainland France. Tourist facilities are well developed and are available on the major islands. Main agricultural productions are coconuts (copra), vegetables and fruits. French Polynesia exports noni juice, a high quality vanilla, and the famous black Tahitian pearls which accounted for 55% of exports (in value) in 2008. French Polynesia's seafloor contains rich deposits of nickel, cobalt, manganese, and copper that are not exploited. In 2008, French Polynesia's imports amounted to 2.2 billion U.S. dollars and exports amounted to 0.2 billion U.S. dollars. There are 53 airports in French Polynesia; 46 are paved. Fa'a'ā International Airport is the only international airport in French Polynesia. Each island has its own airport that serves flights to other islands. Air Tahiti is the main airline that flies around the islands. In 2017, Alcatel Submarine Networks, a unit of Nokia, launched a massive project to connect many of the islands in French Polynesia with underwater fiber optic cable. The project, called NATITUA will improve French Polynesian broadband connectivity by linking Tahiti to 10 islands in the Tuamotu and Marquesas archipelagos. In August 2018, a celebration was held to commemorate the arrival of a submarine cable from Papeete to the atoll of Hao, extending the network by about 1000 kilometres.
