DUBAI DISPATCH — From Blake Hounshell at the World Government Summit: Christine Lagarde, the head of the IMF, made some news here during an interview with CNN’s Richard Quest. Asked what she thought of the Trump administration so far, she said: “From the little we hear, we have reason to be optimistic about growth in the United States,” citing his support for tax reform and infrastructure spending. Pressed on why world leaders didn’t see the populist backlash against globalization coming, Lagarde said: “Because it was insidious. Because it came gradually over time.”
