What is international trade? Literally means international trade. But why Xiamen International Trade? What else does Beijing International Trade have? Who can explain?

International trade is generally understood as international trade. However, there is a place in Beijing called Guo Mao, which is a place name. There are Guo Mao Bridge and Guo Mao Mall, which are used to being called Guo Mao, and everyone knows it. As for the international trade in Xiamen, it may be a place name, I don't know. In fact, there is nothing difficult to understand, how to combine context. But it's hard to say the meaning of the word international trade.
