In 2019 , Papua New Guinea 's real GDP growth was more than 3.5 % , and its inflation rate was over 4 % .
This economic growth has been primarily attributed to strong commodity prices , particularly mineral but also agricultural , with the high demand for mineral products largely sustained even during the crisis by the buoyant Asian markets , a booming mining sector , and particularly since 2009 by a buoyant outlook and the construction phase for natural gas exploration , production , and exportation in liquefied form ( liquefied natural gas or `` LNG '' ) by LNG tankers ( LNG carrier ) , all of which will require multibillion-dollar investments ( exploration , production wells , pipelines , storage , liquefaction plants , port terminals , LNG tanker ships ) .
