The Japanese government has granted more than $1 million of its 2017 budget to support the Khmer Rouge tribunal.
Neth Pheaktra, spokesman for the Extraordinary Chambers in the Courts of Cambodia, said Japan was one of the top donor countries to the tribunal.
“We welcome the fact the Japanese government always gives money to support the ECCC,” he said.
Since the launch of the tribunal, he said Japan had given $86.34 million to the hybrid court, equivalent to 31 percent of the tribunal budget.
Mr Pheaktra said aid from Japan was very important to the Cambodian people.
“It helps seek justice for people who survived the Khmer Rouge, as well as those who died in that era,” he said, adding that the aid would help eliminate the culture of impunity in Cambodia.
It also sends a message to the world that whoever commits crime must be punished and cannot escape the law, Mr Pheaktra said.
Japan meanwhile encouraged the tribunal to continue working on its remaining cases in an accurate, efficient and fast a way as possible, because the accused were getting older and the Cambodian people had been waiting for justice for a long time.
The total budget of the tribunal this year is about $26.5 million, according to an official report.
