PRESIDENT Jiang Zemin has tried to tighten his grip on power by reining in the activities of his rival, former military strongman Yang Shangkun.
Mr Jiang, who chairs the policy-setting Central Military Commission (CMC), has also demonstrated his hold on the People's Liberation Army (PLA) by deploying four army units around the capital on the death of elder Chen Yun on April 10.
An army source in Beijing said Mr Jiang had formed a pact with the CMC vice-chairmen, veteran generals Liu Huaqing and Zhang Zhen, against the possible comeback of Mr Yang, a former state president and CMC secretary-general.
'A politely phrased message has been relayed to Yang asking him to refrain from consorting with PLA officers either in Beijing or the regions,' the source said.
Since his retirement from state and army positions in late 1992, Mr Yang, 87, who enjoys excellent health, has toured the provinces frequently.
In January and February, the former confidant of patriarch Deng Xiaoping was in Guangdong, where he held at least one informal meeting with PLA officers.
