    A sea is always connected to a major ocean yet it is to be covered with lands. Philippines sea is a part of North Pacific ocean which has no clear cut eastern boarder since it roughly stretches to a the major ocean. Where as South Chins sea has clear boarders around. Geographers unanimously agree to it.
