The Philippines has raised the alarm after the number of Chinese fishing vessels in disputed waters in the South China Sea quadrupled last month.
Manila’s military said the number of Chinese ships vessels “swarming” in Iroquois reef, just south of the Reed Bank, had risen to 47 in June from only a dozen in February, threatening the security of the oil and gas-rich Reed Bank.
“China must respect our sovereign rights,” Ariel Coloma, spokesperson for the Western Command, said in a statement.
The Philippines won a landmark arbitration case in 2016 that invalidated China’s expansive claims in the South China Sea, where about $3 trillion worth of sea-borne goods pass every year.
The ruling, which treaty ally United States backs and China refuses to recognise, clarified Philippine sovereign rights in its 200-mile exclusive economic zone (EEZ) to access offshore oil and gas fields, including the Reed Bank, where a natural gas exploration project operated by Philippine firm PXP Energy Corp has been stalled.
US Defense Secretary Lloyd Austin told his Philippine counterpart, Gilbert Teodoro, on Thursday that the US commitment to the defence of its ally was “ironclad”, including in the South China Sea, according to a US summary of the call, drawing a rebuke from China.
“The US defence commitment to the Philippines must not undermine China’s territorial sovereignty and maritime rights and interests in the South China Sea,” Chinese Foreign Ministry spokesperson Wang Wenbin told a regular press conference.
Wang accused the United States of “sowing discord” between countries in the region, while maintaining the actions of the Chinese Coast Guard were legitimate and lawful, and therefore “beyond reproach”.
Wang was not asked about the “swarming”, and there was no immediate comment from the Chinese embassy in Manila about it.
Philippine military said their flights had also recorded the presence of three China Coast Guard ships and two Chinese navy vessels “regularly loitering” at Sabina Shoal, which like Iroquois, is inside the Philippine EEZ.
“These developments raise alarming concerns about China’s intentions and actions within these disputed waters,” WESCOM said.
The Philippines on Wednesday accused the China Coast Guard of harassment, obstruction and “dangerous manoeuvres” against its vessels, after another incident near a strategic feature of the South China Sea.
