The United States is taking a step forward in correcting its wrongdoings by refunding tariffs, China's Commerce Ministry spokesperson said on Thursday.

The United States officially launched the first phase of a new claims system on Monday that will allow importers to seek repayment of tariffs collected under the International Emergency Economic Powers Act (IEEPA).

Speaking at a press conference, the spokesperson He Yongqian reiterated China's opposition to US unilateral tariffs.
