The Chinese vessels swarming around Julian Felipe (Whitsun) Reef in the West Philippine Sea operate from the same port where the ship that rammed and sank Philippine fishing boat FB GemVer in 2019 came from, a US think tank reported. The Asia Maritime Transparency Initiative (AMTI) identified the ships based on photos and videos. The bow numbers and the first two characters were identified from a photo taken by the Philippine Coast Guard patrol on March 7. By cross-referencing the information with vessel profiles in the commercial database Marine Traffic, AMTI identified them as the Yuemaobinyu 42881, 42882, 42883, 42885 and 42886. “These names will sound familiar in the Philippines. In early 2019, the Yuemaobinyu 42212—so named because it operates from the same port as these five – rammed and sank the Philippine fishing vessel F/B Gem-Ver 1 at Reed Bank,” the report said.
