Last week witnessed frequent tariff adjustments, with trade relations showing a diversified trend.

From January 14 to 17, during the Canadian Prime Minister’s visit to China, the two sides reached a consensus on economic and trade cooperation. Canada adjusted its tariff policy on Chinese electric vehicles, ending the levy of a 100% surtax.

The United States imposed a 25% associated tariff on countries with commercial ties to Iran on January 12, and started levying an additional 25% tariff on advanced AI chips such as NVIDIA H200 and AMD MI325X as well as related equipment on January 15. On the same day, the U.S. side sent a friendly signal, stating that the tariff imposition on Iran-related countries would not undermine China-U.S. trade negotiations.

China and the United States also signed the Phase One Economic and Trade Agreement, under which the U.S. side committed to canceling additional tariffs on some Chinese products and reducing the additional tariffs on certain items from 15% to 7.5%.

Starting from January 14, China has imposed anti-dumping duties of up to 113.8% on similar products of some South Korean enterprises. Meanwhile, it has continued to levy anti-dumping duties ranging from 53.3% to 57% on solar-grade polysilicon originating in the United States, with a five-year implementation period.

In this phase, China-U.S. trade relations have been seeking relaxation amid regulation and control. Meanwhile, the targeted tariffs and countermeasures adopted by multiple countries have also highlighted the complexity and game nature of the global trade pattern.
