A Hong Kong conglomerate that’s selling ports at the Panama Canal says it may seek a Chinese investor to join a consortium of buyers.

CK Hutchison said changes to the composition of the consortium and structure of the transaction would be necessary to secure regulatory approval.

Panama’s comptroller general asked its Supreme Court to review the government’s contract extension with CK Hutchison Holdings Ltd.’s local ports unit, potentially throwing a new wrench into the conglomerate’s deal to sell its global terminals business.
