Senior leader of the Communist Party of China (CPC) Liu Yunshan has told officials to follow a code of conduct with "strict" and "honest" as key words.

Liu, a member of the Standing Committee of the CPC Central Committee's Political Bureau, made the remarks Tuesday during a symposium on an upcoming campaign to promote "three stricts and three honests," a series of requirements for officials to improve their life and work raised by President Xi Jinping in March last year.

The slogan refers to: "be strict in morals, power and disciplining oneself; be honest in decisions, business and behavior."

Liu said these are the values CPC members should uphold as the foundation of life and work.

"Both positive and negative examples should be examined, and the problem of'slack and dishonest' must be rectified," Liu said, adding that a special focus will be on making rules and ensuring their implementation.

Stressing that the campaign should integrated into national reform, development and stability, Liu urged leading officials at various departments to set an example by studying and guiding other officials.
