China is showing the United States that it will make good on its trade threats.

CNN Money reported that the Chinese government said that tariffs on about $3 billion worth of U.S. imports are going into effect today (April 2), hitting 128 products ranging from pork, meat and fruit to steel pipes.

It’s the latest move in escalating tensions between the world’s two largest economies, which some experts fear could turn into a trade war.

Beijing says the new sanctions on 128 US products, which it first proposed 10 days ago, are in response to President Donald Trump’s tariffs on imports of steel and aluminum from China and some other countries.

But Trump also has more measures in the works aimed specifically at China. He has announced plans to slap tariffs on about $50 billion worth of Chinese goods following an investigation by his administration into the theft of intellectual property from U.S. companies.
