President Hu Jintao has urged the People's Liberation Army to adopt the political concept of scientific development - a watchword of his rule - in the building of a modernised army. Mr Hu, also chairman of the Central Military Commission, said it was a crucial time for military modernisation as the country endeavoured to build a prosperous society, Xinhua reported. 'We must hold high the banner of Deng Xiaoping's Theory and the important ideals of the Three Represents ... and we must adopt the scientific development philosophy as the key guidelines in the building of national defence and the military,' he said. He made the remarks during a visit on Tuesday to the PLA Daily, the army's mouthpiece, which celebrates its 50th anniversary this year. Mr Hu and his entourage met the newspaper's editors and hundreds of staff, and viewed the paper's website in front of television cameras. Highlighting Mr Hu's undisputed grip on military power, he was accompanied on his visit by nine members of the 11-strong military commission. Navy commander Zhang Dingfa was the only commission member absent. But the report did not give more details. Admiral Zhang, 63, was promoted in 2003 in the wake of a submarine accident that claimed 70 lives. He was made a member of the military decision-making body and a full general in 2004 shortly after Mr Hu took control of the military. The newspaper visit also offered the public a rare glimpse of the military leadership after a recent personnel shake-up involving dozens of senior officers. Confirming earlier media reports, the official PLA website has removed Xiong Guangkai, who was the People's Liberation Army's deputy chief of general staff, from its list of leaders.
