Japan and South Korea will support other Asian nations planning to introduce nuclear power by offering their expertise in formulating safety standards.
This was decided at a meeting in Tokyo on Monday hosted by the International Atomic Energy Agency.
Attending were about 30 delegates from Japan, South Korea, and 6 Asian nations planning to build nuclear power plants, including Vietnam, Thailand and Indonesia.
The meeting agreed that Japan and South Korea will work with Asian countries to compile a set of safety standards in 10 years time for the storage of spent nuclear fuel and nuclear waste disposal.
A Thai delegate expressed hope for the support, saying her country still lags in nuclear waste management and can learn a lot from Japan's technologies.
The move comes as Asian nations increasingly look to nuclear power to sustain their rapid economic growth.
The IAEA wants these countries to promptly establish safety measures needed for operating nuclear plants, including safety standards and government oversight systems.
