A senior Australian politician on Saturday said he was disturbed by the reported efforts of China to infiltrate politics in Australia, Hong Kong and Taiwan detailed by an asylum seeker who said he was a Chinese spy. Resource-rich Australia’s ties with its most important trading partner China have deteriorated in recent years, amid accusations that Beijing is meddling in domestic affairs. The defector, named as Wang “William” Liqiang by the Age newspaper, gave a sworn statement to the Australian Security Intelligence Organisation (ASIO), identifying China’s senior military intelligence officers in Hong Kong, the newspaper said.
