BATANG TORU, Indonesia (AP) — Parts of Asia were reeling after torrents of rain unleashed catastrophic floods and landslides last week, killing more than 1,400 people in Indonesia, Sri Lanka, Thailand and Malaysia. The disaster has also laid bare stark economic disparities in the region.

Indonesia has borne the heaviest blow, recording at least 753 deaths, followed by Sri Lanka with 465. Sri Lankan President Anura Kumara Dissanayake said it’s too early to determine the exact number of dead in his country. At least 185 people in Thailand and three in Malaysia have also been confirmed dead.

Rescue teams on Wednesday were racing against time to reach isolated communities, as more than 1,000 remain missing and as villages lie buried under mud and debris amid ongoing power and telecommunications outages.

Indonesia's President Prabowo Subianto visited a disaster zone Monday, promising aid and support for rebuilding though he has yet to declare a national emergency or sought international assistance like his counterpart in flood-stricken Sri Lanka.

Hard-hit Indonesia and Thailand, both middle-income economies with comparatively stronger fiscal capacity, are able to mobilize extensive rescue operations, deploy military assets and channel emergency funds, while Sri Lanka is responding under far more strained conditions.

Prime Minister Harini Amarasuriya met with diplomats in Sri Lanka last week to urge them to support the government's efforts on relief and reconstruction.

Still recovering from a severe economic crisis, the country faces limited resources, foreign exchange shortages and weakened public services, making a large-scale disaster response significantly more difficult and increasing its reliance on outside assistance.

Authorities in Indonesia, the worst-hit country, said the destruction from days of relentless downpours and a rare tropical storm that pounded the island of Sumatra was the deadliest disaster since the 2018 Sulawesi earthquake and tsunami that killed more than 4,300 people.

Washed-out roads, collapsed bridges and continuing landslides have left rescuers struggling to reach some of the hardest-hit areas, with the National Disaster Management Agency saying about 650 people are still unaccounted for in devastated North Sumatra, West Sumatra and Aceh provinces, where thousands in flooded towns were forced to cling to rooftops and treetops awaiting rescue in previous days.

The agency said Wednesday more than 1.5 million residents have been displaced during the disaster that damaged tens of thousands of homes and public facilities. With some 2,600 people injured and local hospitals overwhelmed, the government has deployed three hospital ships to the devastated provinces.

In Sri Lanka, the flooding is expected to have significant repercussions on the economy, which has only recently stabilized after an unprecedented economic crisis. The island nation is currently under an International Monetary Fund bailout program that requires it to conserve foreign currency to repay defaulted external debt starting in 2028.

Although the full extent of the economic damage is still being assessed, the costs of rebuilding infrastructure, restoring livelihoods and reviving economic activity are likely to put severe pressure on the treasury.

With vast rice-growing regions and the hill country, key suppliers of vegetables, devastated by the calamity, Sri Lanka may be forced to deplete its scarce foreign currency reserves.

Countries such as India, Pakistan and the United Arab Emirates have already launched relief efforts, while other foreign diplomats who met the Sri Lankan prime minister have pledged additional support.

In Thailand, government spokesperson Rachada Dhnadirek announced Wednesday that recovery efforts in southern Thailand are progressing well and that water and electricity have been restored in nearly all affected areas.

She added that the government has disbursed over 1 billion baht ($31.3 million) in compensation to more than 120,000 households impacted by the floods.
