Japan is considering the first large-scale official development assistance in four years for Myanmar to help relieve the impoverished Southeast Asian country's acute power-supply shortages, government sources said Tuesday.

The move comes amid signs that tensions could be easing between the military regime and prodemocracy leader and 1991 Nobel Peace Prize laureate Aung San Suu Kyi and her National League for Democracy.

The ODA under consideration would be for repair work on the superannuated Baluchaung hydroelectric power plant in the eastern province of Kayah.
