Prime Minister Anthony Albanese is confronting a fresh diplomatic dilemma with China: How to fulfill a pledge to regain control of a strategic port without jeopardizing improved relations with his country¡¯s largest trading partner.

Ahead of an election earlier this month, Albanese promised to return to Australian control the Port of Darwin from Chinese company Landbridge Group. It was awarded a 99-year lease in 2015 by the Northern Territory government in a move that sparked criticism from an array of politicians in Australia and in the U.S., which uses a nearby military training facility.

China is Australia¡¯s biggest trading partner by far and previously expressed anger over pressure from the administration of U.S. President Donald Trump concerning the Panama Canal, which resulted in a potential sale by a Hong Kong-based conglomerate of its two Panama port operations ¡ª a deal Beijing has said it will review.
