In Central China's Hunan province, a township official surnamed Yan was stripped of his Party membership for bribing five representatives in a bid to get elected as deputy governor of the township in December 2010, according to the statement.

In addition, the central government will introduce new measures this year to enhance the regulation of city-level officials - such as Party secretaries and city mayors - according to the latest issue of Outlook weekly magazine.

The new moves will come in the wake of discussions held by the Party's Central Political Bureau in late March about how to reinforce the regulation of city-level leading officials in cities, regions, prefectures and leagues.The changes will add to the central government's efforts to better regulate local officials, experts said.

In 2010, the country introduced 20 rules to improve the fostering of Party secretaries of counties that fall under the control of cities.

"The city level plays a transitional role and is a middle layer in the work of the Party and the country," said Ye Duchu, a professor with the Party School of the Central Committee of the CPC.

China has a total of 333 cities, regions, prefectures and leagues, said Ye. City-level leaders are usually involved with complicated issues concerning the adjustment, allocation and balance of interests, he added.
