Cambodia's genocide tribunal to get more Japan funding

Japan has agreed to donate nearly $US3 million to Cambodia's genocide tribunal as it prepares to bring former Khmer Rouge leaders to trial.

A spokeswoman says the funding will go to the operations of the United Nations-backed court's administration office.

Court officials are also in New York this week seeking some $US100 million so the tribunal can continue operations.

They are set to meet potential donors on Friday.

Japan has already contributed more than $US21 million to the tribunal.

The radical Maoist Khmer Rouge regime, which ruled Cambodia from 1975 to 1979, is blamed for the deaths of up to two million people by execution, starvation and excessive work.
