BEIJING, Jan. 12 -- A total of 36,911 cases of frugality regulation violations by members of the Communist Party of China (CPC) were investigated in 2015, China's top disciplinary body said Tuesday.

The CPC's Central Commission for Discipline Inspection (CCDI) said on its website that a total of 49,508 individuals were investigated in those cases, and almost 34,000 were punished through disciplinary measures, according to the CCDI.

They violated the Eight-Point Regulation, which was issued in late 2012, calling for frugality in Party members' work styles and their personal lives.

The most frequent offenses involved the use of official vehicles, accounting for 8,642 cases. Other violations included distributing allowances and sending or accepting gifts or money.

A total of 10 officials at the vice-ministerial level or above were investigated and eight of them were punished with disciplinary measures.

The data were collected through a monthly report system the CCDI has established in almost all provincial regions, centrally administered state-owned enterprises and financial institutions.
