Tensions are already high between the two sides, with China claiming the self-ruled island as part of its territory and threatening to use force to bring it under its control.

Taiwan currently has anti-dumping duties on 10 products, including eight from China, which is its largest trade partner, official data show.

The last time Taipei imposed duties on a Chinese product was in 2023, the ministry said.

In a statement on Tuesday, the finance ministry said it was probing claims that "continuous low-priced exports of Chinese-made beer to Taiwan" was hurting the domestic industry.

China was the biggest source of beer imports to Taiwan last year, Bloomberg News reported, with shipments topping US$125 million last year.

Taiwan was also looking at whether low prices of certain Chinese hot-rolled steel products resulting from "long-standing overcapacity" in manufacturing were harming domestic players, the ministry said in a separate statement.

The move comes after Taiwan's most important security backer Washington raised a blanket tariff on all Chinese goods to 20 percent.
