PRESIDENT Jiang Zemin said farmers had to be lured continuously with tangible material interests in order to keep them under the control of the Communist Party. Mr Jiang, the party's General Secretary, claimed that social disorder, superstition and feudal patriarchal clan system revived and became rampant in some rural areas as the political education of peasants was neglected. To unify the farmers under the party leadership, the party has to organise them firmly and provide better services for them, he said. In his preface to an official textbook on peasants' ideological and political education, Mr Jiang said it was a pressing task for party organisations of all levels to improve the ideological education in rural areas. Despite 'leftist' mistakes made by late Chairman Mao Zedong and the party's Central Committee in the past, Mr Jiang said it was necessary to insist on rural political education. But the party boss warned fellow cadres against shock therapy. They should educate peasants gradually and arouse interest through easily understood teaching materials. Mr Jiang was yesterday quoted by Xinhua (the New China News Agency) as saying patriotism and collectivism had to be stressed. Farmers should be told not to forget the history of foreign aggression and that they had their share of responsibility for the fate of the country, he said. Mr Jiang added peasants had to contribute to the state and protect collective interests although they had been farming under the household contract responsibility system in which they keep part of their production after handing the authorities part. Farmers were also urged to remain thrifty and hardworking even if they got rich. They should invest their money to further expand their agricultural production, Mr Jiang said. Meanwhile, premier Li Peng noted that the country's basic agricultural facilities were relatively backward. And the ability to prevent and fight natural disasters was weak, he added. Problems of poverty among a large number of farmers, high annual population growth and shrinkage of arable land have been restricting the development of farming industry, he said.
