China urged the US to immediately withdraw new restrictions on Chinese testing laboratories and certification bodies, warning it will take necessary steps to defend its interests if Washington “insists on going its own way.”The Chinese Ministry of Commerce said in a statement on Friday that the US Federal Communications Commission has repeatedly introduced restrictions targeting China despite Beijing’s objections, accusing the agency of violating an important consensus reached by the two countries’ leaders. The ministry said the curbs have “severely damaged” the stability of China-US economic and trade relations and disrupted global supply chains.

The FCC voted Thursday to bar testing laboratories, telecommunications certification bodies and laboratory accreditation organizations located in China and other economies designated as “non-reciprocal” from conducting FCC-related testing, certification or accreditation work. The rules will take effect in Dec. 2028.

Beijing said it had repeatedly proposed talks with Washington on a bilateral mutual-recognition agreement, but described the US response as “extremely unconstructive and negative,” according to the Chinese ministry.

The ministry said China’s door remains open to resolving the dispute through consultations, calling on Washington to take industry concerns into account, respect market principles and work with Beijing toward a resolution. It said the measures would raise testing costs and lengthen product delivery and iteration cycles, ultimately hurting US businesses and consumers.
