The communist state backed China newspaper Global Times sent a warning shot to the Trump Administration threatening to take a "tit-for-tat approach" if tariffs are imposed on Chinese products.
China will take a tit-for-tat approach then. A batch of Boeing orders will be replaced by Airbus. US auto and iPhone sales in China will suffer a setback, and US soybean and maize imports will be halted. China can also limit the number of Chinese students studying in the US.
Trump as a shrewd businessman will not be so naïve. None of the previous presidents were bold enough to launch an all-out trade war against China. They all opted for a cautious line since it's most consistent with the overall interests of the US, and it's most acceptable to US society.
Trump cannot change the pattern of interests between China and the US. The gigantic China-US trade is based on mutual benefits and a win-win situation. Even as president, Trump can exert limited influence on it.
If Trump wrecks Sino-US trade, a number of US industries will be impaired. Finally the new president will be condemned for his recklessness, ignorance and incompetence and bear all the consequences. We are very suspicious the trade war scenario is a trap set up by some American media to trip up the new president.
