SHANGHAI (Reuters) - China has passed a regulation ensuring government organizations and private companies have Communist Party units so that party policy can be implemented across society, the People's Daily, the official party mouthpiece, said on Saturday.

The regulation was passed on Friday at a meeting of the Politburo, one of the Communist Party's elite ruling bodies, with President Xi Jinping in attendance.

It was unclear if the regulation, the latest in Xi's campaign aimed at strengthening party discipline, extended to foreign organizations operating in China.
