Scenario description
Assume that on or before the resolution date, a Chinese research or survey vessel again conducts or attempts operations without publicly reported Philippine consent in the Luzon Strait area northwest of Itbayat or comparable northern Philippine EEZ waters, and Philippine state assets operationally interdict, disrupt, escort away, block, force departure, or otherwise prevent that activity. The geography is the northern Philippine EEZ around the Luzon Strait, including waters near Itbayat and undersea cable corridors if reported. The entities are Chinese research or survey vessels, any accompanying Chinese maritime assets if reported, and Philippine Coast Guard, navy, maritime-surveillance, fisheries, or other state assets. The known scope and magnitude are limited to the reported vessel presence, attempted or ongoing survey/research activity, and the reported Philippine enforcement action; exact survey equipment, data collected, duration, number of support vessels, cable-corridor proximity, and commercial disruption remain unavailable unless stated in the resolving report.
