Senior Associate Justice Antonio Carpio has renewed his call for the Duterte administration to file new protests against China for its incursions in waters within Philippine territory. Carpio argued that filing of protests against China is necessary to protect the sovereignty of the Philippines over its exclusive economic zones in the West Philippine Sea that Chinese ships have already reportedly penetrated. “We won in the (arbitration court in) The Hague because we filed several, numerous protests, note verbales protesting China’s incursion in the West Philippine Sea. Had we not made those protests against China’s nine-dash line map on time, we would have lost,” he explained.
