London (CNN Business) 1. US-China friction: Shares in Chinese surveillance company Hikvision plunged on Wednesday following a report that the Trump administration is considering banning it from buying US goods.

Hikvision stock plummeted the daily limit of 10% during early morning trading in Shenzhen. It recovered some of those losses to close about 6% lower.

The drop came after the New York Times reported that the United States is considering adding the company to a trade blacklist, alongside smartphone and 5G giant Huawei.

The move would be Washington's latest attempt to curb Beijing's tech ambitions, and a further escalation of the US-China trade war as talks have stalled.

Hikvision manufactures surveillance cameras and security products powered by artificial intelligence. It's faced international criticism for surveillance operations in Tibet and Xinjiang. US lawmakers last year urged sanctions against the company and accused it of helping China create a "high-tech police state."
