Philippines Says China Vessel Conducting ‘Illegal’ Research Near Gas-Rich Reed Bank

MANILA, May 7 (Reuters) – The Philippine ⁠Coast ⁠Guard has accused China ⁠of conducting illegal marine scientific research near ​the oil and gas-rich Reed bank within Manila’s exclusive ‌economic zone in the ‌South China Sea, according to a Thursday statement.

“We ⁠will ⁠continue to challenge any illegal activities that undermine our ​sovereignty and sovereign rights,” PCG commandant Admiral Ronnie Gil Gavan said.

• PCG aircraft spotted Chinese research vessel Xiang Yang ​Hong 33 near Iroquois Reef during a maritime patrol ⁠on May ⁠6.

• The PCG ⁠said ​the Chinese vessel was seen deploying a service boat toward ​the reef, confirming ⁠the ongoing “unauthorized” research operations.

• One Chinese Coast Guard vessel and 13 Chinese maritime militia ships were also seen around the reef, it added.

• It said the ⁠Chinese research vessel departed China on April 15 and conducted ⁠operations near Second Thomas Shoal, Sabina Shoal, Mischief Reef, and Jackson Atoll in recent weeks.

• The PCG also monitored 28 Chinese maritime militia ships near Thitu island during the same maritime patrol.

• The Philippines said China had no authorisation to conduct the marine research and called it a violation ⁠of Philippine sovereign rights as well as the United Nations Convention on the Law of the Sea.

• Beijing’s embassy in Manila did not immediately respond ​to a request for comment.
