SIEM REAP, Cambodia (AP) 鈥� En Poy was minding cattle in a former stronghold in Cambodia when he set off his first land
mine.
The blast from the rusty relic he picked up cost him an arm and an eye. It also inspired his career with the nonprofit Cambodian Self Help Demining, which clears land mines and unexploded ordnance across the country, deadly remnants of wars from the last century.
Groups like Poy鈥檚 that rely on foreign aid are struggling as donors shift funding for humanitarian demining toward active conflicts in , and , and to more recent wars, like in and . Today’s conflicts are also driving higher defense spending, leaving less money for aid.
President Donald Trump鈥檚 and a last year worsened the problems, though American has restarted.
Cambodia’s predicament shows that dangers remain even when fighting ends. Demining groups say that without international support, Southeast Asia鈥檚 unfinished work clearing land mines and unexploded bombs will continue to endanger communities, maiming and killing people and slowing development for years to come.
Poy was wounded in a second that pierced his face and body with shrapnel and killed three of his colleagues. He now educates fellow Cambodians in high-risk areas on how to avoid such dangers. But he’s not sure how long that will last.
鈥淚f one day donors stop funding my organization, I would definitely be sad because we haven’t finished our job,” he said. “There are still a lot of landmines left over.”
The Vietnam War’s deadly legacy
The bled into neighboring Cambodia and Laos, triggering strife that lasted long after the Americans fled the , including the Khmer Rouge鈥檚 , which killed about 1.7 million Cambodians.
Cambodia is one of the world’s most . Laos is the most per capita in history and Vietnam still battles the .
Since the wars ended, land mines and unexploded ordnance have killed approximately 90,000 people and wounded almost twice as many across the three countries.
Leftover weapons lie beneath fields and forests, blocking construction of roads and schools. They are by children who account for more than 40% of the civilian casualties recorded globally since 1999 by the Landmine and Cluster Munition Monitor, formed by nonprofit groups to track such issues.
Demining is slow and painstaking work.
Teams first survey and map contaminated areas. Then step-by-step they clear vegetation, using metal detectors and specialized equipment to locate explosives and destroy them. Progress is measured in meters (feet) a day and work often stops in wet weather.
鈥淭hese things don鈥檛 really become less dangerous with time. They become more dangerous as they deteriorate,鈥� said Charles Ray, a Vietnam War veteran who became the first post-war U.S. consul general in Ho Chi Minh City and later ambassador to Cambodia.
By funding demining, the U.S. proved it cared, Ray said. 鈥淲e鈥檙e not just this behemoth that comes in with our military machine and breaks things, we can also help nations rebuild,鈥� he said.
Modern conflicts pull funds from Southeast Asia
Funding for humanitarian demining amounted to $4.3 billion from 2020 to 2024, according to the land mine monitor.
National contributions from affected countries made up about a fifth and foreign aid provided the rest, with most of the funds from the U.S., Germany, the European Union, Norway, and Switzerland, the land mine monitor says.
Recent conflicts are creating unprecedented demand for demining as contaminated areas expand, said Maria Vardis of the U.N. Mine Action Service.
Ukraine received a third of all humanitarian demining funding in 2024, more than any other country, the land mine monitor found. Other active conflict zones, like and , received increased funding, while demining efforts in , and have also ramped up, while some Asian nations are getting less funding.
Germany is considering reducing foreign aid in favor of and .
At the same time, more land mines are being planted and bombs dropped in other conflicts such as the and .
鈥淔unding does fluctuate year to year, but in the big picture, even in the face of cuts by many governments, the big crises continue to be funded, but smaller and older mine action projects are struggling,” Vardis said.
Pause in U.S. aid rattled trust built over decades
Under Trump, U.S. demining aid to Southeast Asia has yo-yoed. That has 鈥渟et a really dangerous precedent for what can be done,鈥� said Danae Hendrickson of the U.S.-based advocacy group Legacies of War.
Last year, the U.S. approved $56.5 million for war-legacy programs in Vietnam, according to congressional documents, compared to $197 million allocated in 2024. In July, Secretary of State Marco Rubio announced $130 million in demining assistance for Southeast Asia, without giving details.
Last year’s freeze briefly halted war-legacy projects in Vietnam and weakened Hanoi鈥檚 confidence in U.S. commitments, said Nguyen Khac Giang, a visiting fellow at Singapore鈥檚 ISEAS鈥揧usof Ishak Institute.
鈥淭he lasting damage is to the hard-earned trust between the two former enemies,鈥� he said.
In an email to The Associated Press, a U.S. State Department spokesperson said American assistance is 鈥渘ot charity鈥� and that humanitarian demining aid will continue to serve U.S. interests around the world.
Cambodian demining group faces closure
Between 1992 and 2025, about 1.2 million mines and 3.2 million other explosive remnants of war were found in Cambodia, according to the Cambodian Mine Action and Victim Assistance Authority.
The country still had 1,749 square kilometers (about 675 square miles) of uncleared land as of last year.
Thousands or even millions more weapons may still be out there, said Bill Morse, president of the Landmine Relief Fund, which supports Cambodian Self Help Demining.
Barely an hour from the famed temple complex in Siem Reap, deminers with South Korean, Swiss and American flags on their uniforms and helmets, recently inched through a minefield, clearing the land one painstaking step at a time.
They found a Soviet-designed anti-personnel land mine. Another unit nearby was dispatched to destroy a mortar round and a rocket-propelled grenade at a cassava farm just off a highway leading to a .
The group may have to stop their work by September due to sharp cutbacks in donations. 鈥淲e have simply run out of donors,” Morse said.
鈥淚f people want to pull their money away, that鈥檚 a decision that they have to make,” he said. “But when they do, people will die here.鈥�
