Vietnam's ruling Communist Party in October instructed government authorities to revise plans to build nuclear power plants with Russian and Japanese assistance with a view to delaying them due to the government's tight finances, it was learned Sunday from party and government sources.

The government is now working on a comprehensive revision of the plan and intends to submit a report to the National Assembly, according to the sources.

According to one of the sources, a considerable investment at the present time is "extremely difficult" given the financial situation of the government.
