The former chief of China’s national reserves bureau is being investigated for alleged serious violations of law and discipline, the country’s top anti-graft authority said on Wednesday.

The Central Commission for Discipline Inspection (CCDI) was investigating Zhang Wufeng, the former head of the National Food and Strategic Reserves Administration, according to a statement posted on the commission’s website.

Following a statement that it was investigating a top official from the central bank for alleged violations of discipline and rules, China’s Communist Party dismissed a state-owned insurer’s CEO accused of graft last month.
