Communist Party authorities are planning a fourth plenary session of the Central Committee, which may take place as early as the end of this month. A party source said the plenum's top concerns would be to form a unified summation of the past 20 years of reform and to set the direction for future change. The plenum may endorse a document being drafted under the direction of Premier Zhu Rongji, summing up the experience of Deng Xiaoping's initiatives. President Jiang Zemin, who is also party General Secretary, is due to deliver a major speech on the party's priorities for the 21st century. 'Since the party held the third plenum only in October, it is unusual for it to convene another plenum so soon,' the source said. 'However, Jiang and Zhu feel they must have a new consensus to push forward the more difficult stages of reform.' The plenum will assess the next phase of reform in areas such as state-owned enterprises, banking and foreign trade. Mr Zhu is particularly anxious to keep up the momentum of economic reform. Political analysts said seeking a consensus was difficult because many reforms on the agenda had exacted large-scale social costs such as unemployment. The analysts said senior cadres, including Central Committee members, had difficulty summing up the past, let alone settling on common goals for the future. For example, they said, views differed on the contributions of the likes of Deng's lieutenants, such as the two disgraced former party general secretaries Hu Yaobang and Zhao Ziyang. Leftist or Maoist leaders, including Deng Liqun, wanted to blame the pair for 'bourgeois liberalisation'. Mr Jiang hoped the document would focus on the achievements of the mid-to-late 1990s, for which he could claim credit. However, liberal and moderate cadres had argued that the accomplishments of the 1990s could not have been possible without the contributions of the two ousted party bosses.
