The top leadership of the Communist Party of China (CPC) Wednesday adopted a document to standardize the benefits of CPC and state leaders, such as their offices, housing and staff.

The document was passed at a meeting of the Political Bureau of the CPC Central Committee presided over by Xi Jinping, general secretary of the CPC Central Committee.

A statement released after the meeting hailed the new rules as "an expansion and upgrade" to the Party's eight-point guidelines against bureaucracy and extravagance introduced four years ago.

Party and state leaders should vacate their offices in a timely manner after retiring, the statement said.

They should "travel without pomp" and minimize impact on public life, and not have vehicles exceeding the set standards, it read.

Leaders should have the right size of staff as stipulated. They must step up education and management of their staff and strictly constrain their relatives and personnel.

They are also urged to limit their vacations and strictly abide by the relevant approval system.

The Political Bureau of the CPC Central Committee will be first to follow the new rules.

The statement said the new rules are of significant importance to the improvement of the party's working style, showing that the CPC Central Committee with Comrade Xi Jinping as the core is leading by example.

It ordered related departments to draft detailed plans to implement the new rules and strengthen supervision, stressing that they should be implemented without compromise.

"To forge an iron, one must be strong oneself," it said.

"The strict governance of the Party should start from officials, especially senior ones," it said. "Whatever you demand others to do, you should do yourself first; whatever you forbid others to do, you should firmly forbid to yourself."
