China has protested the visit by Manila's defense and military chiefs to a disputed island in the South China Sea, but the Philippine government maintained Saturday that it owns the territory where Filipino troops and villagers have lived for decades.
The public argument comes amid a thaw in once-frosty relations between the neighbors after Philippine President Rodrigo Duterte took office last June and moved to rekindle Manila's friendship with Beijing, which has been strained by the long-seething territorial disputes.
Philippine Defense Secretary Delfin Lorenzana and military chief of staff Gen. Eduardo Ano flew to the island, which Filipinos call Pag-asa, with dozens of journalists Friday to inspect an eroded airstrip. The Philippine government plans to reinforce and lengthen the airstrip and build a dock starting next month to accommodate ships with construction materials, Lorenzana said.
About 1.6 billion pesos ($32 million) has been earmarked for the construction, including a fish port, solar power installation, water desalination plant, improved housing for soldiers, and facilities for marine research and tourists.
Internationally known as Thitu and called Zhongye Dao by China,iIt's the second-largest island in the South China Sea's hotly contested Spratlys archipelago.
In Beijing, Foreign Ministry spokesman Lu Kang expressed China's displeasure over the high-profile Philippine visits to the island, saying China was "gravely concerned about and dissatisfied" by the island visits and adding.
The Philippine government replied by saying the island was part of an island municipality under its western province of Palawan, which faces the disputed waters.
During the trip to Pag-asa, Chinese forces tried to drive away two Philippine air force planes that carried Lorenzana, Ano and others as they flew near a Chinese artificial island called Subi, just 25 kilometers (15 miles) away.
Lorenzana said their aircraft continued uninterrupted without any incident after Filipino pilots messaged back to the Chinese that they were flying over Philippine territory. The Chinese warned the Philippine aircraft they were entering the periphery of Chinese installations and told to avoid miscalculation.
The Chinese navy has similarly warned US ships and aircraft to leave what Beijing claims as its territory, messages which the Americans also ignored.
China claims virtually the entire sea and has aggressively tried to fortify its foothold by transforming in recent years seven mostly submerged reefs into island outposts, including Subi. Three of the artificial islands were built with runways, along with buildings, towers, radars and more recently weapons systems, to the consternation of other Asian claimant governments and the US, which insists on freedom of navigation in international waters.
