Papua New Guinea

0% --:--

Papua New Guinea hosts one of Earth's last true megadiversity frontiers: 7% of global species on less than 1% of land area, with 850+ languages making it the world's most linguistically diverse nation. The economy mirrors this fragmentation—growth reached 3.8% in 2024 driven primarily by non-resource sectors (4.5%), while the reopened Porgera gold mine underperformed expectations, limiting resource sector growth to 1.7%. LNG exports comprised 43% of total exports, positioning PNG as a critical Asian supplier.

The resource pipeline represents potential transformation—or continued frustration. TotalEnergies' $10 billion Papua LNG project has been delayed from mid-2024 to late 2025 or early 2026 after contractors quoted 40-50% more than expected. As of early 2025, no long-term offtake agreements had been concluded. ExxonMobil's P'nyang project entered pre-FEED in Q2 2025, with Santos' Agogo field connection potentially reaching FID by 2026. Gold exports doubled in value from 2021 to 2024 (21% of total exports), buoyed by higher global prices.

The non-resource economy proved more reliable: cocoa, coffee, copra, and fisheries drove agricultural exports while the government pursues fiscal repair—deficit narrowing to 2.6% of GDP Targeting balance by 2027. PNG's challenge is converting extractive wealth into lasting development before resources deplete. Like an old-growth rainforest where most nutrients cycle through living biomass rather than accumulating in soil, the economy risks exporting value without building productive capacity that persists after extraction ends.
