The estimated revenue from tourism in May 2022 was $43.5 million, data showed. For the first five months of 2023, the tourism revenue totaled $827.8 million, marking a substantial increase of 30.4 per cent compared to the same period of last year when it stood at $634.6 million, according to the official data.

Tourism, one of Sri Lanka's leading foreign exchange earners, suffered a setback due to the Covid-19 pandemic and economic and political crises in the South Asian country. /IANS
