The significance of the water price, to both countries, is Singapore’s existence as a sovereign nation separate from Malaysia, and the sanctity of the most solemn agreements which Singapore and Malaysia have entered into. - Prof Jayakumar

What I'm quite puzzled is (I'm sorry Singaporean friends), how can you claim to be a sovereign nation by being belligerent about a price hike? Singapore is, as admitted, dependent on Malaysia for half its water supply. Dependency does not lead to sovereignity.
