On 30 March, separatist rebels opened fire on three employees of the Grasberg gold and copper mine near Puncak Jaya – the highest mountain in Indonesia’s remote easternmost province of Papua. One worker was killed and another two sustained gunshot wounds in the attack, which targeted an office and housing area of US-based firm Freeport-McMoRan. The company jointly owns the site – which is the largest gold mine and second largest copper mine in the world – with the Indonesian government.

The mine sits at the heart of a volatile region. The Papua region, which encompasses the provinces of both Papua and West Papua, has been the site of a low-level separatist insurgency since the 1960s. Seven years after the end of Dutch colonial rule, the region was incorporated into Indonesia in 1969 via a disputed referendum, in which only 1,025 Papuans, carefully chosen by the Indonesian military, were permitted to cast a ballot. The poll remains a source of tension and drives separatism to this day.

While the conflict has persisted at a low level for decades, last year – the 50^th anniversary of the vote – witnessed an uptick in violence. Protestors took to the streets across the two provinces last August, angered by an incident in Surabaya in which Papuan university students were arrested by police and suffered racial taunts from nationalists, over accusations they had desecrated an Indonesian flag. The ensuing street demonstrations soon turned violent, with deaths and injuries reported on both sides.

The recent shooting incident near Puncak Jaya was preceded by a series of clashes in the area between rebels and the Indonesian military, which prompted 917 residents to flee to the nearby city of Timika. Violence appears to be rising while the political campaign for Papuan independence stalls, leaving the status quo intact and the future no clearer for the region’s residents, who have long endured poverty and underdevelopment. As the stalemate persists, what makes the situation in Papua so intractable?

The roots of the independence movement

The origins of the dispute date to the mid-20th century, when the area was under Dutch colonial rule. Indonesia gained Independence in 1949, yet the Dutch retained control of Papua through the 1950s. As calls for independence grew, Papuan leaders held a Congress in 1961 and raised their own flag, the Morning Star. Violence erupted between Papuans, Indonesians, and Dutch forces until a UN-sponsored treaty – the New York Agreement – was brokered in 1962. The agreement facilitated initial Indonesian control with the promise of a future referendum to decide the final status of the disputed territory.

The ballot, labelled the ‘Act of Free Choice,’ was held in 1969. The Indonesian authorities selected just 1,025 Papuan representatives to vote, by raising of the hand, on behalf of the entire population of the region, which at the time had almost a million inhabitants. Voters unanimously backed staying under the rule of Jakarta; yet they did so within an atmosphere of intimidation and under the threat of violence. The result was controversially ratified by the UN, which voted by a majority 84-0, with 30 abstentions.
