What do you think would happen if we stopped buying their exports or their currency fell so low that they could no longer import raw materials? China's economic growth is unsustainable.
They will sell to the africans, latin americans, indians, russians, persians, and arabs. If you don't want china's good stuff, someone else will. People make it sound as if china is forcing them to buy. China have never pointed a gun at anyone and said buy or else. In fact, if china were to stop selling to your country, you will become a nation of people with no underpants. Whose loss will it be then ?
