Australia exports more goods to china than any other country it trades with. these goods include such things as iron ore, coal, crude petroleum, and wool. in turn, australia imports goods like computers, cars, and refined petroleum from china. this is an example of how promotes trade.
a tariff
a quota
specialization
productivity

This is an example of how a quota promotes trade.

- China is the place with productivity since it's like the "power source" most places trade with it whereas Australia uses the produce and turns it into the new gen. technology.

- A tariff is when a certain tax has to be paid from importing things.

- Specialization is for places that make use of native things, they specialize on certain things for instance some places are know for their tech., some for farming and irrigation.

- A quota is when there is a fixed share amongst the traders. Like in the paragraph it mentioned how china gives to australia and australia gives a balance back.

Hope this heps and have a great day!
