Philippines Challenges Chinese Survey Ship Near Gas-Rich South China Sea Reef
Manila– The Philippines said on Thursday it issued radio warnings to a Chinese research vessel operating near a disputed reef in the South China Sea, accusing Beijing of conducting unauthorized marine scientific activities in waters claimed by Manila.
The Philippine Coast Guard said it deployed aircraft on Wednesday to monitor the Chinese research ship Xiang Yang Hong 33 near Iroquois Reef in the Spratly Islands, where it observed the vessel launching a service boat toward the reef.The coast guard said the operation “confirmed ongoing unauthorized marine scientific research activities” within waters over which the Philippines claims sovereign rights and jurisdiction.
Iroquois Reef lies at the southern edge of Reed Bank, an area believed to contain substantial natural gas and oil reserves and long viewed as strategically significant for Manila’s energy security.
During the aerial patrol, Philippine authorities also reported spotting 41 vessels identified as part of China’s “maritime militia” anchored near Iroquois Reef and around Thitu Island, a Philippine-controlled outpost in the Spratlys inhabited by about 400 civilians and home to a recently established coast guard station.“The Philippines has not granted such consent to the People’s Republic of China for any marine scientific research activities in these waters,” the coast guard said in a statement.
It added that the presence of the research vessel alongside the concentration of Chinese maritime militia ships represented “a serious infringement on Philippine sovereign rights and maritime jurisdiction.”China’s embassy in Manila defended the activities, reiterating Beijing’s longstanding claim of “historic rights” over much of the South China Sea and asserting that the islands and reefs concerned were Chinese territory.
The embassy said Chinese research vessels had carried out their missions “in accordance with international law.”The Xiang Yang Hong 33, a research vessel capable of supporting deep-sea submersible operations, departed China more than three weeks ago and has since been tracked near several Philippine-claimed features in the Spratly chain, including Sabina Shoal and Second Thomas Shoal, both recurring flashpoints between the two countries.
Tensions between Beijing and Manila have intensified in recent years as China expanded coast guard, naval and maritime militia deployments across the contested waterway, where competing territorial claims overlap with key shipping lanes and potentially resource-rich seabeds.
China claims nearly the entire South China Sea despite a 2016 ruling by the Permanent Court of Arbitration in The Hague that found Beijing’s sweeping claims had no legal basis under international law. China has rejected the ruling.
