They all go by sea, and the owner of the sea is a Japanese company. The price of the sea is controlled by a kind of financial futures, which is controlled by Wall Street in the United States.
Many so-called modern steel mills in China must use high-quality iron ore, which is expensive and mainly produced in Australia.

It's really complicated Look how many traps the Japanese, Australians, British and Americans have set for China, haha.
