CK Hutchison said it may invite a ¡°major strategic investor¡± from China to join a group seeking to buy its global ports, as the Hong Kong-based company works toward a solution that pleases all in the geopolitically sensitive deal.

The unnamed investor would join as a significant member of the consortium, the company said in a stock exchange filing Monday, hours after the expiry of a 145-day exclusive talks window with the group backed by American asset manager BlackRock.

¡°Changes to the membership of the consortium and the structure of the transaction will be needed for the transaction to be capable of being approved by all relevant authorities,¡± CK Hutchison said, adding that it ¡°intends to allow such time as is required for such discussions.¡±
