MANILA (REUTERS) - The military has blocked a group of lawmakers and security chiefs from visiting one of nine Philippine-held features in the disputed South China Sea due to safety issues, defence officials said on Friday (March 17).
But one senior Philippine general said the cancellation of this week's trip to Thitu Island, known locally as Pagasa, had more to do with concerns over how China would react.
Thitu is close to Subi Reef, one of seven manmade islands in the Spratlys that China is accused of militarising with surface-to-air missiles, among other armaments.
The Philippines has squabbled with China for years over the South China Sea, but relations have improved under Philippine President Rodrigo Duterte, who was to meet Chinese Vice-Premier Wang Yang on Friday afternoon.
Five members of the House of Representatives were due to fly to Thitu on Thursday, while Defence Minister Delfin Lorenzana and military chief General Eduardo Ano were also planning a separate visit on Friday.
The lawmakers had planned to assess upgrades and new facilities needed for the Filipino fishing community of about 100 people living on the island in the Spratly archipelago.
The military said the trip was postponed due to "safety issues". Defence ministry spokesman Arsenio Andolong said landing on a porous runway after heavy rains was too dangerous.
"We will need at least five days of dry weather to harden and make it safe again for landing planes," he said. It was not clear when the trip would be rescheduled for.
But Lieutenant-General Raul del Rosario, who heads the Philippine Western Command, said there were concerns about how China would view the trip to Thitu.
"That is contested area, that is not 100 per cent ours," he said in a Congressional hearing on Thursday. "That's why we are concerned if you fly there. Every time an aircraft flies there, it gets a warning and, there are times, they fire flares towards the aircraft."
The military declined to comment on Lt-Gen Rosario's statement.
Maintaining and funding communities on islands in the Spratlys is seen by the Philippines and Vietnam as an essential measure in staking claims of sovereignty. China has soldiers on islands it occupies.
China claims most of the South China Sea, a strategic waterway through which about US$5 trillion (S$7 trillion) of goods passes each year. Brunei, Malaysia, the Philippines, Taiwan and Vietnam also have claims.
The Philippines has been wary of provoking China and wants to keep the peace and avoid jeopardising billions of dollars of promised Chinese business deals and investments.
