The US is reportedly considering blacklisting Chinese surveillance tech firm Hikvision

The U.S. administration is considering limits to Chinese video surveillance firm Hikvision’s ability to buy U.S. technology, the New York Times reported on Tuesday, in a move that deepens worries about trade frictions between the world’s two top economies.

The move would effectively place Hikvision on a U.S. blacklist and U.S. companies may have to obtain government approval to supply components to Hikvision, the paper said.

The U.S. Commerce Department blocked Huawei Technologies from buying U.S. goods last week, effectively banning U.S. companies from doing business with the Chinese firm, a major escalation in the trade war, saying Huawei was involved in activities contrary to national security.

The White House did not immediately respond to a request for comment on the report.
