Hong Kong announced Wednesday that its postal service would no longer send packages to the United States, in response to the White House’s plan to charge tariffs on small, low-value parcels from the city.

Nineteen global law firms had closed their Hong Kong practices by 2023. FedEx opted to ship its regional headquarters to expat-friendlier Singapore. So did other multinationals, from L’Oréal, a French maker of posh cosmetics, to Lidl, a German cut-price retailer. LVMH started running its luxury labels from the mainland.
