BUENOS AIRES, Argentina (AP) — Argentina and the United States said they reached an expansive trade deal on Thursday, boosting Argentine President Javier Milei as he moves to open up the South American nation's notoriously protectionist economy and reflecting the close alliance between the radical libertarian and U.S. President Donald Trump. Argentina's foreign minister, Pablo Quirno, posted a selfie on social media showing him and several Argentine diplomats beaming after emerging from a meeting in Washington where he said they'd signed the pact. “Congratulations to our team and thanks to the U.S. Trade Representative’s team for building this great agreement together,” Quirno wrote.
