Outside Europe landlocked states are poor: 16 are extremely poor and another 16 very poor. The Sustainable Development Goals (SDGs) recognise their lack of sea-Access as a major cause of their reduced chances of escaping poverty and reaching the stated goals. This paper proposes including corridors to the sea and other forms of sea-Access among the SDGs. It also discusses objections to doing so that appeal to the rejection of global egalitarian arguments, to the possibility of compensating those countries for their disadvantage rather than removing it, and to the territorial rights of the coastal countries. The paper concludes that none of these objections to the corridors, and a fortiori to the less ambitious remedies of the Almaty and Vienna Programmes, withstands scrutiny.
