THE Communist Party has called on officials at all levels to give full support to the policy of democratic centralism to ensure party policies are strictly enforced, according to an official report. Speaking at a national organisation work conference, a deputy head of the party's Organisation Department, Zhang Quanjing, said the party leadership should be strengthened to further boost the ''consciousness'' of officials at all levels in implementing the policy of democratic centralism. ''[They should] correctly handle the relationship between the parts and the whole, regions and central authorities as well as short-and long-term interests,'' Mr Zhang said. Policies adopted by the party, he said, must be enforced in their entirety in order to uphold the authority of the central leadership. According to Xinhua (the New China News Agency,) Mr Zhang urged cadres to tighten control over party organisations and step up indoctrination among party members at the grass-roots level. This would serve as a ''stable and strong organisation guarantee''for the smooth implementation of reform, he said. The strengthening of the work-style of the leadership should be co-ordinated with the battle against graft. He indicated that greater efforts were needed regarding the grooming and selection of middle-age and young cadres to take up senior positions in the party and government bodies. ''We have to smash barriers, particular those based on seniority.'' The official vowed to create a sound environment for the emergence of young talented people to serve the Government. Mr Zhang said a major revamp of the personnel system would be launched to set up a cadre management system. Under the new system, the recruitment and promotion of cadres would be based on a set of ''open, fair and competitive'' criteria, he said. This would be beneficial to the ''rational allocation'' of manpower resources, said Mr Zhang. Furthermore, the official said more channels would be established to supervise the work of cadres and there would be a set of diverse methods for training cadres. Mr Zhang said the scope of the practice of swapping cadres among different regions would be extended this year.
