Taiwanese voters approved a referendum to maintain a ban on food products from five Japanese prefectures, imposed after the 2011 Fukushima nuclear power plant disaster, dealing a setback to the government of President Tsai Ing-wen and possibly damaging the island's relations with Japan.

The Central Election Commission website showed that a total of 7.79 million people approved the initiative against 2.23 million who were in opposition.

The referendum result is legally binding and government agencies must take necessary action.
