The PLA was yesterday urged to crank up its public relations machinery after the second misunderstanding in recent weeks. Democratic Alliance for the Betterment of Hong Kong vice-chairman Gary Cheng Kai-nam called on the army to install a spokesman to allay public concern. He was speaking after the People's Liberation Army said rumours it had banned buses entering Stanley Fort were unfounded. The hiccup follows the incident involving the head of the advance party, Major-General Zhou Borong, who refused to produce a permit at the border. A Xinhua (New China News Agency) official had assured him the PLA understood the need for better media communication, he said. A spokesman for the Chief Executive-designate's office said: 'The idea of setting up some sort of media unit has been discussed and movement has been made in the sense that they now think it is a good idea.' General Zhou's driver clashed with Customs officials after their car was stopped for routine checks returning from Shenzhen on May 27. Language problems were said to have exacerbated a 'misunderstanding'. The most recent row centres on moves by transport chiefs to curtail bus services to Stanley Fort on July 1, leaving hundreds of pupils at nearby St Stephen's College stranded. Newspaper reports said the PLA did not want 14 and 6A buses entering the barracks. But Xinhua told Mr Cheng the PLA had merely informed transport chiefs they did not need the service for their soldiers. A hotline, 2580 3567, along with an e-mail address A72239520*netvigator.com were set up by Democrats yesterday to allow the public to lodge complaints against the PLA.
