Papua New Guinea

Introduction

Papua New Guinea, located in the southwestern Pacific, is a nation characterized by its rich cultural diversity and complex history. The eastern half of the island of New Guinea was divided between Germany (north) and the UK (south) in 1885. The latter area was transferred to Australia in 1902, which occupied the northern portion during World War I and continued to administer the combined areas until independence in 1975. Since 2001, the island of Bougainville has enjoyed a degree of autonomy, with many national powers devolved to the region, reflecting the ongoing evolution of governance and self-determination in this unique archipelago.

Recent economic challenges include a collapse in betel nut prices, tighter monetary policy, and improved foreign-exchange availability, which have collectively contributed to declining inflation rates.
