CK Hutchison Holdings Ltd. shares dropped the most in nearly two weeks after reports that Hong Kong billionaire Li Ka-shing is considering delaying the signing of a controversial deal to sell the company’s Panama Canal ports to a consortium including BlackRock Inc.

China slammed the Hong Kong-based firm for portraying the agreement as “purely commercial in nature” and condemned the pact as “a tool to enforce US hegemony”.

Authorities in all 23 countries where ports operate expected to conduct competition reviews if they find them legally necessary, source says.
