- City's top-ranking official targeted by Xi's graftbusters
- Ai was previously chairman of Baosteel's listed subsidiary
Ai had appeared in public as recently as Nov. 6, when he attended an industrial exhibition in Shanghai.
The case was an indication that Xi’s anti-graft campaign was finally reaching the upper echelons of regions that had been largely spared, including the political power centers of Beijing and Shanghai. CCDI announced Wednesday that Lu Xiwen, a deputy party secretary for Beijing, was being investigated for disciplinary violations, the highest-ranking municipal official swept up in the crackdown.
