Which country is Australia most closely connected with?

As a second language, I suggest you learn the following article in Japanese. You can see that Australia is now the second largest trading country in the world, with high economic growth and low inflation in the past decade. Because Australia is close to the Asia-Pacific region, and since the establishment of the European Union, Britain's foreign trade has no longer been particularly preferential to Australia, and its trade focus has begun to shift to its Asian neighbors. At present, Asia ranks first in Australia's foreign trade, accounting for 60% of its export market. Among the top ten trading partners, the United States and Japan are the top two, and more than half of the other eight are Asian countries, which shows that communication dependence is getting stronger and stronger. The main reason is that its import and export projects are complementary rather than competitive with Asian neighbors, especially the trade volume with Chinese mainland has surpassed other Asian countries, which deserves close attention.
