The China Securities Regulatory Commission has reportedly launched comprehensive on-site inspections of financial institutions, a move seen as a sign that the anti-corruption campaign is widening into the securities and financial sectors.

The regulator will investigate 200 financial institutions including securities firms, mutual funds and private equity funds, focusing on possible wrongdoing such as bribery and embezzlement, the Economic Observer reported, citing a senior executive of a PE firm.

The CSRC on Monday did not respond to China Daily's questions on the report.
