Sydney – A Pacific island chain with a bloody recent past has taken its first formal steps to becoming the world’s newest nation, seeking to forge a path to prosperity in a region where Western powers are increasingly concerned about China’s burgeoning influence.

More than two decades after Bougainville’s bitter civil war ended, and almost three quarters of a century after American and Australian forces liberated the islands from Japanese occupation, the province of some 300,000 people voted overwhelmingly in recent weeks to secede from Papua New Guinea.

On Friday, the referendum results were presented to the acting governor-general of Papua New Guinea in Port Moresby, the seat of government that has controlled the province since 1975.
