China's top economic planning body said the national anti-corruption campaign sent shockwaves through the organization as it "played hardball" in institutional reform and administration was streamlined throughout the past year.

Xu Shaoshi, minister of China's Development and Reform Commission (NDRC), said all administrative approvals submitted to the commission could be handled and checked online, during a press conference on Thursday.

Eleven NDRC officials were charged with taking bribes last year and Xu said the image of the ministry was "bloodied" by the scandals.

The NDRC for so long operated behind closed doors opened a more transparent public office in January where applicants can submit basic information and make appointments.

Xu said 76 percent of the national commission's items for approval had been abolished or transferred to lower-level authorities, in 2014.

The minister has high hopes for the public office and said the ministry will further open-door reforms by reducing approvals to 2 or 3 and put all applications online during this year.

"Key posts responsible for approval authority, money and assets are rotated," said Xu, adding major price reform measures are being considered now.
