SINGAPORE — Asia-Pacific stocks were mixed in Thursday morning trade, with shares of Chinese tech giant Alibaba in the spotlight following reports that Chinese regulators will probe the firm for suspected monopolistic behavior.

Alibaba shares in Hong Kong fell around 5% in early trade on Thursday.

That came following reports that Chinese authorities will probe the Alibaba Group over suspected monopolistic behavior. CNBC has yet to confirm the reports, which were made by Bloomberg and Chinese state media outlet Xinhua. Separately, Alibaba-affiliate Ant Group also confirmed Thursday that it had “received a meeting notice from regulators.”

The news comes on the heels of an increasing — and largely unexpected — push by Chinese authorities to rein in their biggest tech firms through regulatory action.

In the broader Asia-Pacific markets, stocks were mixed in Thursday trade.

Meanwhile, in Brexit trade deal negotiations between Britain and the European Union, bond yields and the British pound jumped on Wednesday following reports that an agreement was close. Reuters reported that a trade deal was “imminent,” citing a senior EU diplomat, though CNBC could not independently verify this.

The British pound was at $1.353, having fallen to around $1.32 earlier in the week.

The moves stateside came after U.S. President Donald Trump criticized the new U.S. Covid-19 relief package, an act that could delay the deployment of funds to struggling Americans.
