China and the African Union dismissed on Monday a report in French newspaper Le Monde that Beijing had bugged the regional bloc's headquarters in the Ethiopian capital.

An article published Friday, quoting anonymous AU sources, reported that data from computers in the Chinese-built building had been transferred nightly to Chinese servers for five years.

After the massive hack was discovered a year ago, the building's IT system including servers was changed, according to Le Monde. During a sweep for bugs after the discovery, microphones hidden in desks and the walls were also detected and removed, the newspaper reported.
