Nations observers recognizing the elders were placed under duress and forced to vote yes. The Free Papua Movement (OPM) has engaged in a pro-independence conflict with the Indonesian military since the 1960s. This has been in response to the initial take over of the region and multiple killings and other human rights violations by Indonesian troops, causing many West Papuans and international organisations to describe the situation in West Papua as "genocide". Rebellions occurred in remote mountainous areas in 1969, 1977, and the mid-1980s, occasionally spilling over into Papua New Guinea. In 1980, the Trans Irian Jaya Highway, currently Trans-Papua Highway, began construction. The highway would link unconnected cities and regions across the region, which were previously only accessible by sea or, for inland areas, by air. However, some experts suggested prioritizing development of local indigenous people over infrastructure development in order to be parallel with non-Papuan migrants, who were progressively inhabiting Western New Guinea's cities at the time. In the post-Suharto era, the national government began a process of decentralisation of the provinces, including, in December 2001, a special autonomy status for Papua province and a reinvestment into the region of 80% of the taxation receipts generated by the region, in addition of special autonomy fund. In 2003, a new province of West Papua was created from the western regencies of Papua (province), comprising lands in the Bird's Head Peninsula and surrounding islands to its west. In 2011, Indonesia submitted an application for membership to the Melanesian Spearhead Group (MSG) for the two Papua provinces (as well as 3 other melanesian dominated provinces) and was granted observer status. The West Papua National Council for Liberation independence movement made an unsuccessful application for membership to the MSG in 2013 after which the United Liberation Movement for West Papua (ULMWP) was established in December 2014 to unite the three main political independence movements under a single umbrella organisation. In June 2015, the ULMWP was granted MSG observer status as representative of West Papuans outside the country while Indonesia was upgraded to associate member. In 2016, at the 71st Session of the UN General Assembly, leaders of several Pacific Island countries called for UN action on alleged human rights abuses committed against Papua's indigenous Melanesians, with some leaders calling for self-determination for West Papua. Indonesia accused the countries of interfering with Indonesia's national sovereignty. In 2017, at the 72nd Session, the leaders
