美国有线新闻 CNN 中国对美国128项进口商品加征关税（在线收听）

CARL AZUZ, CNN 10 ANCHOR: For CNN 10, I'm Carl Azuz. We are 10 minutes of world news explained.

That starts today with tensions over trade between the U.S. and China.

The Asian country announced yesterday that it was putting tariffs or taxes on about $3 billion worth of imports from the U.S. The tariffs are on 128 American-made products, ranging from pork and fruit to steel pipes. This will make it more expensive for America businesses to sell those products in China. And China says this was done as a response to the tariffs that the U.S. recently put on imports of Chinese steel and aluminum.

Meanwhile, U.S. President Donald Trump says more tariffs, new ones worth as much a $50 billion are being planned by the U.S. on additional goods from China.

So, one big question is, will all this cause a trade war, when countries ta?ke turns putting tariffs on each other's goods, causing prices to rise?

We don't know yet. The U.S. and China ship hundreds of billions of dollars of goods back and forth every year. So, the tariffs we've seen so far are a tiny part of that. And America's treasury secretary says the U.S. and China are talking behind the scenes about how to prevent a possible trade war.

But a number of experts are concerned this could turn into one and so are some stock investors. The Chinese tariffs were a major factor in a drop of the U.S. stock market yesterday when the Dow Jones Industrial Average fell 459 points. But just like it's hard to tell if a trade war is on the horizon, it's also hard to tell what kind of effects one could have decades down the road.
