Security network looks at closing inequalities

China's social security network - which covers the largest number of people in the world - is focusing on shortening the gaps between urban and rural, developed and less-developed regions, said a nationwide audit.

The National Audit Office's report, released on Thursday, concluded China has "basically" established a social security management system from 2005 to 2011.

The report inspected the operation of 18 security funds in 2,790 counties, 404 cities and 37 province-level regions over that period.
