Proposals to lift pension ages in order to ease China's financial burden have renewed public debate over changing the retirement age.

A new plan from Tsinghua University suggests raising the pension age for men and women to 65 as of 2030. The retirement age for men is 60 and for women 50.

The proposed age is based on the pace of aging in China, said Yang Yansui, director of the Tsinghua Center for Employment and Social Security, adding that raising the pension age does not mean an adjustment to the retirement age.
