A decade ago, a Chinese company was given the green light to take control of the Darwin port, which is key Australian infrastructure. 

Now, the Albanese Government is scrambling to get it back in Australian hands, in a move that risks antagonising China, while being welcomed by the United States.

He explains why the deal was allowed in the first place and whether Chinese control really poses a risk to national security.
