China has accused the US of violating trade agreements.

China’s recent trade countermeasures on US-related issues were a necessary defense, Chinese Commerce Ministry officials said.

China urged the US to stop threatening to raise tariffs and warned of retaliation if Washington continued to press. Beijing said Washington should return to talks to resolve trade disputes, Bloomberg reported.

US President Donald Trump on Friday announced an additional 100% tariff on Chinese goods and restrictions on exports of “any critical software” from November 1. This came after China imposed new port fees for American ships, launched an antitrust investigation against Qualcomm Inc. and announced sweeping restrictions on exports of rare earth metals and other critical materials.

China explained that these actions were defensive in nature and were a response to new restrictions from the United States after the talks in Madrid in September. They emphasized that constant threats of high tariffs “is not the right way to interact with China” and that Beijing “will take resolute measures to protect its legitimate interests.”

Last week, China introduced new export restrictions on rare earth metals and other strategic materials. Now, foreign exporters using even a small amount of Chinese rare earths require an export license. Equipment and technology for rare earth processing and magnet production are also subject to control.

Before making decisions, China notified other countries about them through bilateral export control mechanisms.

Beijing said that it had assessed in advance the possible impact of the restrictions on industrial and logistics chains and considered it minimal. China also stated its readiness to maintain dialogue with partners to maintain the stability of global supplies.

The new port fees for American ships came into effect at the same time that the United States plans to impose new tariffs on large Chinese ships calling at American ports.

China stressed that American measures against Chinese maritime, logistics and shipbuilding companies harm China’s interests and negatively affect the atmosphere of bilateral negotiations.

As a reminder, US President Donald Trump canceled a meeting with Chinese President Xi Jinping and threatened Beijing with large tariffs for restricting the export of rare earth metals.
