The value of Asia's stock markets has fallen. It is the biggest fall in decades. Shanghai's market was down nearly 8%. Japan's fell 7.8%. An analyst called it a "bloodbath". Stock prices fell after the USA announced trade tariffs on April the 2nd. President Trump said that was the day "we began to make America wealthy again".

A Chinese newspaper said China has had "eight years of trade wars with the US". It said China would beat "US tariff bullying". China could put its own tariffs on the USA. Japan will ask the USA to reduce the tariffs. President Trump said the tariffs were like medicine. He said they would fix things.
