From Asia Times:
BTW they never paid compensation to Vietnam or Laos either.
The article is long so I copy parts:Cambodia, US duel over Vietnam War debt
Washington's demand that Phnom Penh repay a four-decade-old US$500 million loan will likely push the post-conflict country even closer to China

Since US President Donald Trump’s inauguration in January, Cambodian Prime Minister Hun Sen has repeatedly called on the new American leader – often personally – to cancel a US$500 million debt owed dating back to the Vietnam War. Hun Sen has made the request to previous US presidents, to no avail. He has referred to the money owed as “blood-stained” and “dirty.”
Between 1972 and 1974, the US Department of Agriculture gave the then ruling pro-US Lon Nol regime US$274 million, officially for food supplies, but most believe it was really used for military purposes. Lon Nol came to power in a US-backed military coup in 1970, only to fall to the Maoist radical Khmer Rouge regime five years later.
So US paid their dictator Lon Nol $274 million but failed to keep him in power, they never paid any compensation for the immense damage they did to the country and now want to get the money back they paid to their own creature and with interest.Hun Sen has noted that around the same time the debt was incurred the US dropped more than 2.7 million tons of ordnance on Cambodia, making the country one of the most heavily bombed per capita in the history of warfare. “It is difficult for us to tell Cambodians to accept debt to buy bombs and bullets to kill Cambodian people,” Hun Sen said recently.
