Prosecuting departments have been handling an increasing number of cases involving bribery offered by multinational companies to government officials or State-owned enterprises, according to the Supreme People's Procuratorate.

"The worst-hit areas in terms of corruption are pharmaceuticals, the electric power sector and software," Song Hansong, director of the procuratorate's corruption prevention department, told China Daily.

The number of bribery cases being prosecuted has risen markedly across the country, Song said, but he declined to give further details.
