BEIJING, Oct. 25 (Xinhua) -- Senior Chinese leader Zhou Yongkang Monday called on the country's law enforcement and judicial agencies to safeguard social justice and improve their credibility.

Zhou, member of the Standing Committee of the Political Bureau of the Communist Party of China (CPC) Central Committee and secretary of CPC Central Commission for Political and Legal Affairs, made the remarks at the commission's group study.
