Two former top officials with the Ministry of Civil Affairs have received disciplinary punishments including demotion and early retirement for failing to supervise subordinates, China's top anti-corruption body said on Wednesday.

Former minister of civil affairs Li Liguo and former vice-minister Dou Yupei were responsible for the "systematic corruption" in the ministry, the Central Commission for Discipline Inspection said in a statement.

Different from other corrupt senior officials in the past, Li and Dou's wrong was not "supervising their subordinates effectively". So far, public attention has been focused on the mismanagement of welfare lotteries.
