Senior Shenzhen cadres are being asked to declare their income and assets in a move intended to clean up provincial government. Forms are being distributed to about 500 chief and senior officers at the bureau level. They are required to report all sources of incomes, business investments, ownership of property and cars and gifts they have received. The Shenzhen move forms part of an image-boosting drive in the special economic zone as Hong Kong's handover approaches. The practice, roughly the same as the declaration system for Hong Kong's civil servants, coincides with a recent appeal by Beijing for clean government. The central Government has recently announced a new set of regulations asking senior cadres and party secretaries to report their businesses and assets. But now, some provinces have introduced a similar system for lower-ranking officials. A Shenzhen Municipal Government spokesman said: 'The new rule aims to strengthen the management of government units and promote spiritual civilisation among officers.' Officials will have to make a declaration each year, but the information will not be published. 'Those failing to report properly will be reprimanded,' the spokesman added. A senior Shenzhen security official was recently punished after discipline inspectors found 10 bottles of Louis XIII XO cognac in his home. The bottles, which he claimed were gifts from friends, cost about HK$15,000 each - 10 times the monthly salary of an average Shenzhen bureau chief. In Hong Kong, civil servants have long been required to register their income and business interests with the Government. The system covers all officials down to personal assistants at directorate or secretariat level. The material is also made public. The new Shenzhen move is the latest in a number of recent initiatives to boost the image of the Government. The Shenzhen Commission for Discipline Inspection and Supervision Bureau has ordered officers not to use public money for banquets or gifts. Guangdong Public Security Department has also issued a circular banning officers from drinking wine while on duty. Last month, Shenzhen police announced 10 performance pledges to improve frontline officers' attitudes. Under the scheme, offices will be staffed around the clock and officers will provide services without demanding gifts or money.
