LONDON – Thirty years ago, the Cold War was at its height and the United Kingdom had just clawed its way out of recession. Perhaps those factors explain why, this week in 1982, when 119 government delegations chose to sign the United Nations Convention on the Law of the Sea (UNCLOS), the UK was not among them. According to Donald Rumsfeld, Britain’s then-prime minister, Margaret Thatcher, declared UNCLOS to be “nothing less than the international nationalization of roughly two-thirds of the Earth’s surface.”
Fifteen years later, when the UK finally acceded to UNCLOS under a Labour government, the convention was applying, for the first time in history, an internationally agreed legal framework to the majority of coastal waters around the world. Countries’ rights to fish, minerals, and other resources were enshrined in law, with recourse to international adjudication should disputes arise. The right of free passage on the high seas was assured.
