(NYTimes) - The Chinese government hit back Monday at President Trump’s tariffs on steel and aluminum by acting on a threat to put tariffs as high as 25 percent on imports of 128 American-made products, including pork and seamless steel pipes.

The Chinese Ministry of Commerce indicated that the tariffs, which it first publicly suggested almost two weeks ago, were intended to pressure the Trump administration to back down from a simmering trade war. In addition to imposing additional tariffs on steel and aluminum from China and other countries, President Trump has threatened to put protective duties on other Chinese-made products worth $60 billion.

“We hope that the United States will rescind its measures that violate World Trade Organization rules as quickly as possible,” the ministry said in an online statement about China’s retaliatory tariffs. “China and the United States are the world’s two biggest economies, and cooperation is the only correct choice. Both sides should use dialogue and consultation to resolve their mutual concerns.”
