Is the water coming from the grounds of Itu Aba (Chinese name: Taiping; Philippine name: Ligaw) suitable for drinking?
The answer to this question is crucial in determining whether Itu Aba is an island or a rock.
The determination of Itu Aba’s feature- whether a rock or an island- is important in establishing the extent of the Philippine’s territory and coverage of its sovereignty.
Itu Aba, occupied by Taiwan, is the biggest feature in the Spratlys in South China Sea which is being claimed wholly by China and Taiwan and partly by Philippines, Vietnam, Malaysia and Brunei.
The United Nations Convention on the Law of the Sea or UNCLOS defines an island as “a naturally formed area of land, surrounded by water, which is above water at high tide.”
