Hong Kong billionaire Li Ka-shing has raised Beijing’s ire by agreeing to sell its control over ports in Panama to appease President Donald Trump. But there may be little the Chinese authorities can do to punish him for it.

The US$23 billion sale is not final, but needs no Chinese or Hong Kong approval, leaving CK Hutchison to decide whether to proceed, analysts say.

Shares of Hong Kong conglomerate CK Hutchison slid more than 6% on Friday after China's Hong Kong and Macau Affairs Office posted a commentary in state media criticising the company's recent port sale as a betrayal of China.
