(COMBO) This combination of pictures created on August 22, 2026 shows US President Donald Trump in Washington, DC, on July 13, 2026 and Canadian Prime Minister Mark Carney on August 22, 2026. Canadian Prime Minister Mark Carney announced retaliatory tariffs on the United States on August 22, after walking away from a "bad deal" on trade in a deepening rift between the longtime allies. Negotiations between the neighboring countries broke down August 21 in Washington, putting into force new 50-percent US tariffs impacting about $20 billion worth of goods, or 5.5 percent of Canadian exports to the United States.
