The ministry is accepting public comments within 20 days of Jan. 7, according to an unofficial translation, and expects to conclude the investigation within a year. The announcement came one day after the ministry announced new dual-use export controls against Japan, which were imposed in response to Japanese Prime Minister Sanae Takaichi saying that a Chinese invasion of Taiwan could potentially trigger a military response (see 2601070002).

China last week released its catalog of dual-use goods that will be subject to both import and export licenses for 2026, according to an unofficial translation of a Ministry of Commerce notice.

Japan recently launched an investigation on whether to renew its antidumping duties on certain potassium hydroxide from South Korea and China, according to an unofficial translation of a notice from the country's Ministry of Economy, Trade and Industry.

They are set to expire in August, and the investigation is expected to be completed within a year. Japan said potassium hydroxide is used as a raw material for chemical fertilizers and detergents.

Thailand on Jan. 1 will end its import duty exemption for low‑value goods, which for years exempted imports worth less than about $45, according to the Hong Kong Trade Development Council.

The tariffs are levied on top of the current rate and apply to imports of beef over a set quota of 2.7 million metric tons in total from all countries. The quota for U.S. imports is 0.164 million tons in the first year and will increase to 0.171 million tons by the third year.

Beijing is ordering its chipmakers to use at least 50% domestically made equipment for adding new semiconductor capacity as part of a push to build a self-sufficient semiconductor supply chain, Reuters reported Dec. 30. Chinese chipmakers seeking approval to build or expand their chip plants have been told in recent months that they "must prove through procurement tenders that at least half their equipment will be Chinese-made," the report said. The directive is forcing Chinese manufacturers to choose domestic suppliers "even in areas where foreign equipment from the U.S., Japan, South Korea and Europe remain available."

China on Dec. 26 sanctioned 20 U.S. defense firms and 10 executives in response to the State Department's approval of a host of arms sales to Taiwan earlier this month (see 2512180008).

The sanctions block their assets in China and prohibit them from carrying out transactions with people or companies in China.
