The Australian government questioned at least one Chinese journalist in Australia in late June, according to reports in Chinese and Australian media, amid heightened tensions between the trading partners.

At least one Chinese journalist in Australia was questioned by the Australian Security Intelligence Organization on June 26, the Sydney Morning Herald reported Wednesday, citing senior Australian security sources it didn’t identify. This was in connection with the investigation of a state lawmaker, the sources said.

New South Wales state lawmaker Shaoquett Moselmane had his home and office raided by police on June 26. He later said the probe was linked to people allegedly advancing the goals of the Chinese government, and denied being a suspect.
