US President Joe Biden has banned more Chinese firms which supply or support Chinaโ€™s military and security apparatus.

Former US President Donald Trump prohibited Americans from buying stakes in 31 Chinese companies and now Bidenโ€™s move on Thursday has expanded the blacklist to 59.

According to a White House statement, the latest batch of sanctions target companies involved in Chinese surveillance technology used to โ€œfacilitate repression or serious human rights abuses,โ€ which โ€œundermine the security or democratic values of the United States and our alliesโ€.

It has been reported that the initial list published under the administration of former US President Donald Trump included major telecoms, construction and technology firms such as China Mobile, China Telecom, video surveillance firm Hikvision, and China Railway Construction Corp.

The move has left the ties between the US and China severely strained.

Ahead of the release of the US blacklist on Thursday, Beijing repeated its outrage over the blacklist of Trump administration and vowed to protect the rights of Chinese companies.

Beijing claimed the blacklist was โ€œpolitically motivatedโ€ and โ€œignores the facts and actual situationโ€ of the firms involved.

Foreign ministry spokesman Wang Wenbin said at a routine briefing that the ban โ€œseverely undermines normal market rules and orderโ€ and โ€œdamagesโ€ฆ the interests of global investors, including US investorsโ€.

Previously, the sanctions and choice of targets were tied to a congressionally mandated Defense Department report.

According to reports, the ban on new investments will come into effect from August 2 at 12:01 am in New York.

Reports said among the defence companies on Joe Bidenโ€™s list are Aviation Industry Corp. of China, Ltd., which is one of the best known of the Chinese military giants; China North Industries Group Corp.; China Aerospace Science and Industry Corporation Ltd. and China Shipbuilding Industry Co.

The blacklist of Biden also includes Hangzhou Hikvision Digital Technology Co., the developer of surveillance cameras and facial-recognition technology that has helped Chinese authorities roll out โ€œsafe cityโ€ initiatives in Xinjiang where ethnic Uyghurs have faced persecution.
