Ji Jianye, mayor of Nanjing, capital of east China's Jiangsu Province, is under investigation for suspected discipline and law violations, the discipline watchdog of the Communist Party of China (CPC) revealed on Thursday.

Ji is also deputy secretary of the Nanjing municipal committee of the CPC, according to the CPC Central Commission for Discipline Inspection.

Ji, a Jiangsu native, became acting mayor of Nanjing in 2009 and has served as Nanjing mayor since January 2010.

Ji's case follows the investigation and punishment of a list of high-level officials in the latest anti-corruption campaign, which include Jiang Jiemin, former head of the State-owned Assets Supervision and Administration Commission and Liu Tienan, former vice head of the National Development and Reform Commission.

In early July, former Railways Minister Liu Zhijun was given a suspended death penalty for taking bribes and abusing his power.

The CPC leadership considers corruption one of the most pressing and serious problems that the Party must solve.

Chinese President Xi Jinping vowed to go after both "tigers" and "flies," or high-ranking and low-level corrupt officials, as well as constrain political power within a "cage of regulations."
