BlackRock has agreed to buy two major ports on the Panama Canal from their Hong Kong-based owner as part of a $22.8bn deal, following pressure from Donald Trump over alleged Chinese influence at the vital waterway.

Under the agreement, the ports’ Hong Kong-based owner CK Hutchison would sell the business to a consortium including BlackRock, Global Infrastructure Partners and Terminal Investment Limited, according to a company statement on Tuesday. The group would acquire a 90 per cent stake in the company that owns and operates the two ports in Panama.

Trump has frequently alleged that “China is running the Panama Canal”, and rattled Panama when he threatened earlier this year to “take it back” under American control. The Trump administration has also demanded Panama reduce Chinese influence at the canal, claiming Beijing’s involvement in the ports had violated a treaty concerning its neutrality.
