U.S. President Donald Trump has hailed a deal led by U.S. firm BlackRock to buy most of the $22.8 billion ports business of Hong Kong conglomerate CK Hutchison, including assets it holds along the Panama Canal. The deal will give the U.S. consortium control of key Panama Canal ports amid White House calls to remove them from what it says is Chinese ownership. But it also risks heightening tensions between the U.S. and Panama, which have tussled over Trump’s claims about the Canal.
