A unified system to deal with reports of officials failing to do their duty could be established as part of the fight against corruption, China's top prosecuting authority said on Thursday.

The Supreme People's Procuratorate also announced that it will improve procedures and measures in regards to crimes related to dereliction of duty — ensuring every interrogation and seizure is recorded.

The country's top prosecutor Cao Jianming said reports of duty-related offenses will be dealt with in a timely manner.

Cao highlighted the importance of anti-corruption, asking every prosecuting body to communicate more with media and encourage public supervision.

Over the past five years, Chinese prosecutors have investigated 97 former officials of minister-level or above, and recouped economic losses of about 48.7 billion yuan ($7.9 billion).

Of the investigated officials, 60 were accused of corruption by prosecutors, including Zhou Yongkang, the country's former top security chief, who was sentenced to life imprisonment for graft, abuse of power and disclosing State secrets last year.

During the same period, prosecutors also investigated 4,164 officials whose actions had contributed to disasters such as the fatal blast in Tianjin and the deadly landslide in Shenzhen, Guangdong province last year.

In addition to fighting graft in external departments, prosecutors cracked down on graft in their own system, the statement said, adding that they had punished 1,267 prosecutors who breached the law or related codes of discipline in recent years.
