BEIJING has further eased restrictions on the activities of ousted party chief Zhao Ziyang, the ''spiritual leader'' of the Communist Party's liberal wing. Chinese sources said yesterday Mr Zhao had received more visitors in his central Beijing house. Most visitors were his former associates, many of whom still retained considerable influence in the party and the Government. Several visitors reported that the 74-year-old former general secretary was healthy and in a good mood. They said Mr Zhao had made a trip to the northeast in autumn and he and his wife played golf at a course near the Ming Tombs ''with increasing frequency''. The conditions of relatives - a few were reported to have come under investigation soon after the crackdown on June 4, 1989 - had also improved. The former party boss lives with his daughter, a hotel manager, and her husband, Wang Zhihua, an officer in the People's Liberation Army (PLA). Having been transferred out of the PLA's high-powered Equipment Procurement Department soon after the massacre, Mr Wang recently finished a course at a military academy. He is expected to be given a relatively senior PLA post or to go into business. Mr Zhao's youngest son, Zhao Xijun, a businessman based in the United States since 1989, has returned to China with more frequency. ''While in China, the younger Zhao spends most of his time in Hainan Island, where most of his business interests are,'' a source said. Mr Zhao's eldest son, also a businessman, is believed to be based in Hong Kong. The former party boss, however, still has to report to the top leadership for trips outside Beijing. He is barred from Guangdong province. Western diplomats said a number of Mr Zhao's former associates, including Electronics Minister Hu Qili, had also been active. They said the chances of Mr Zhao returning to power were slim but he could become ''an influential kingmaker'' after the death of patriarch Deng Xiaoping. Meanwhile, diplomatic sources said Mr Deng had mended fences with former state president and military strongman Yang Shangkun. ''Yang and Deng parted ways late last year after the patriarch removed his military powers and those of his stepbrother Yang Baibing,'' a source said. ''Since the summer, however, the two old chums have resumed part of their friendship.'' The source said Mr Deng's major motive in the reconciliation was to ensure that Mr Yang, the most healthy of the so-called Eight Immortals in the party, would support President Jiang Zemin after his death. The patriarch was particularly anxious to prevent Mr Yang from forming a power bloc with Mr Zhao to back Mr Jiang's rivals such as National People's Congress Chairman Qiao Shi.
