(CNN)Australia's ambassador to China says he has been denied entry to the Beijing trial of an Australian TV host accused of sharing state secrets, the latest development in an opaque case analysts worry may be politically motivated.
Australian ambassador denied entry to Beijing trial of Australian TV host Cheng Lei
Cheng Lei, a former business anchor of China's state broadcaster CGTN, is accused of illegally supplying state secrets overseas, a charge that carries a possible sentence of between five years to life in prison.
Australian ambassador to China, Graham Fletcher, told media it was "deeply concerning, unsatisfactory and regrettable" he had been denied entry to the trial, which was due to start Thursday.
"We can have no confidence in the validity of a process which is conducted in secret," he said, adding that Australia had no information about the charges or allegations against Cheng.
"That is part of the reason why we're so concerned because we have no basis on which to understand why she's been detained."
A heavy security presence including uniformed police and plain-clothed security personnel were outside the No. 2 People's Intermediate Court in Beijing where Cheng was to be tried, Reuters reported. Police, who had taped off areas close to the north entrance of the court, checked journalists' IDs and asked them to move away.
Cases related to national security are typically tried behind closed doors in China.
Australia's Foreign Affairs Minister Marise Payne said Canberra had been advised Cheng would stand trial on Thursday, and had asked that Australian officials be permitted to attend the hearing.
Cheng has been in custody since August 2020, and observers have raised concerns over the secretive court process. Payne says Cheng has been allowed regular access to Australian consular officials, who last saw her on March 21.
Chinese authorities have not revealed details of the allegations against Cheng, but the country has a nearly 100% conviction rate, meaning it was "almost set in stone" that a guilty verdict will be handed down, said Elena Collinson, a senior researcher at the University of Technology Sydney's Australia-China Relations Institute.
Australia's ambassador to China was last year denied entry to the espionage trial of Australian blogger Yang Hengjun, who remains in custody.
The Australian government says it has regularly raised issues with Beijing over Cheng's detention, but Chinese authorities say the judiciary handles cases in accordance with the law.
The lack of transparency over the case and backdrop of deteriorating relations between China and Australia has prompted concerns that the case could be political.
"Even allowing for circumstances in which the case brought against her has some substance, it is just very difficult to believe that tensions between Australia and China haven't in some way affected or factored into this case," Collinson said.
"It may well be that the number of years in the sentence will be tailored to send some sort of political message," she said. "(The verdict) will just fuel the already acute distrust that many Australians feel with respect to Beijing."
