Tonga

Tonga is a small island developing state whose economy depends on remittances, agriculture, tourism and external assistance. The country is highly exposed to natural disasters, including cyclones and volcanic events, which periodically disrupt growth and strain public finances. Recent development efforts have prioritised resilient infrastructure, renewable energy expansion and public financial management reforms. Strengthening private sector development and improving connectivity are central to supporting inclusive growth, while climate adaptation remains a core long-term policy challenge.
