The "Tigers" in Xi Jinping's Anti-corruption Campaign

After Xi's assumption of office, an unprecedented number of vice-ministerial-level-and-above incumbent officials have been investigated for corruption charges, including Vice Chairman of the Chinese People's Political Consultative Conference Su Rong and Xu Caihou, a retired vice chairman of the Central Military Commission. Many of these probed officials have worked in the security and legal system, the petroleum industry, the Ministry of Land and Resources or the Sichuan province where Zhou Yongkang once held key positions.
