The Armed Forces of the Philippines reported on Tuesday that its navy monitored 31 Chinese coast guard and naval vessels in the West Philippine Sea. The surveillance covered the period from October 13 to October 19. The vessels were observed around four key maritime features in the area. The count was up from 27 Chinese vessels recorded during the previous week. That represented an increase of four vessels over the earlier reporting period. Rear Adm. Roy Vincent, the AFP spokesperson for the West Philippine Sea, announced the figures.
