中国商务部周六敦促美国停止扩大对美国对华投资的限制，称一项关于敏感技术的拟议规则将破坏贸易关系。
The Chinese commerce ministry urged the United States on Saturday to stop expanding restrictions on American investments in China, saying a proposed rule on sensitive technologies would disrupt trade ties.
美国财政部周四发布提案，更新其对外投资安全计划，将生物技术列入受限领域，并扩大了高性能计算和高超音速系统的覆盖范围。
The US Treasury Department issued proposals on Thursday to update its outbound-investment security programme, adding biotechnology to restricted sectors and expanding coverage of high-performance computing and hypersonic systems.
北京商务部在一份声明中表示，该提案“具有歧视性”地扩大了与中国相关的投资限制，并加强了管控。
Beijing's commerce ministry said in a statement that the proposal "discriminatorily" widened China-related investment restrictions and intensified curbs.
声明补充称，中方坚决反对美方提案，并保留采取未具体说明的反制措施的权利。
It firmly opposed the US proposal and reserved the right to take unspecified countermeasures, it added.
北京还表示，该提案将损害双边经济关系，并与两国元首达成的共识相悖，两国元首在过去六个月内已会晤两次。
Beijing also said the proposal would damage bilateral economic ties and ran counter to the consensus reached by the countries' presidents, who have met twice in the past six months.
美国财政部表示，这些措施不仅针对中国，旨在阻止美国资本支持外国对手发展可能威胁美国国家安全的两用战略技术。
The US Treasury has said the measures, which do not only cover China, are intended to stop US capital from supporting foreign adversaries' development of dual-use strategic technologies that could threaten US national security.
美国该计划此前已限制涉及中国的某些美国投资，涉及半导体、量子技术和人工智能领域。
The US programme had already restricted certain US investments involving China in semiconductors, quantum technologies and artificial intelligence.
