Vietnam last year abandoned plans to build its first nuclear power plants with Japanese and Russian assistance due to heightened concern over the safety of atomic power following events including the Fukushima disaster, according to former President Truong Tan Sang.

"The situation in the world had changed," Sang, 68, said in an interview in Ho Chi Minh City on Thursday. "Due to the fluctuations of the world situation, the Vietnamese people were very worried, especially the people in the area where the nuclear power plants were to be located. They had reactions. Therefore, we had to temporarily halt (the plans)."

The interview was his first with a foreign media outlet since stepping down from the post in April last year.
