BEIJING, Jan 12 - China will focus its corruption crackdown on preventing misconduct from escalating into graft, according to a state broadcaster documentary series that highlighted the crimes of a disgraced former minister.

The first episode of the CCTV-produced series titled "Unwavering in Our Resolve, Unyielding in Our Step" aired late Sunday,  a day before China's top anti-graft watchdog, the Central Commission for Discipline Inspection (CCDI) kicked off its three-day annual meeting.
