Sierra, 1) There is no problem with the Chinese owning a port. It doesn’t give them any rights. They cant take it home.
The government can make rules on who can use the port, what they are charged, how its run, who can be a director, what a foreign director can be excluded from knowing.
Consider a gas pipeline or power grid; The owners dont determine any of these things. All they have a right to is the distribution of profits that the directors choose to make.
2) The Chinese don’t have to “invade” Australia to take over. They don’t need to send the young warriors in landing craft to take over our cities. Catch a train into the Sydney CBD and you may be the only non Chinese on the train. Back home the party knows where their family lives.
