In official business news, UK based PR businessware (PEBW) has better China coverage because its PR-XinHua joint marketing agreement.
US based Businessware (part of Warren B's empire) has weak converage in Asia outside Japan and Australia.
Other than PRBW and BW, I prefer Reuters for its business news in China. It has not only the official news, but it has the gut to report "under the cover" stories.
