In the struggle for power and influence in the Pacific, there is one man Australian security agencies have their eye on.

He’s allegedly a member of a powerful organised crime network spanning the Pacific. And, according to secret intelligence documents out of Canberra, he’s a potential threat to our national interest.

Why? Because he’s also a senior member of the Chinese Communist Party. And his alleged activities are taking place amid China’s growing influence in the Pacific.

All this comes at a time when a security agreement between Beijing and the Pacific Island nation of Fiji, once put on ice, now seems to be back on the table.

Today, investigative journalist Nick McKenzie on his story with The Age, The Sydney Morning Herald and 60 Minutes on Zhao Fugang, and why his influence in Fiji matters to Australia.

And just a note, there is no suggestion by our mastheads that Zhao Fugang is a convicted criminal or is guilty of the allegations, only that he is of such serious concern to Australia’s security agencies he has designated as a high priority target.
