Donald Trump signs a proclamation introducing tariffs on imports of steel and aluminium. Canada and Mexico are exempt indefinitely. We get reaction from Nicholas Lardy of the Peterson Institute for International Economics in Washington DC. On International Women's Day, we hear about a girl empowerment initiative in Kano, Nigeria. And the president of Mauritania, Ameenah Gurib, tells us what it's like being Africa's only female national leader. Plus, Emily Bates at the 大象传媒's technology programme Click tells us why some of Amazon's Alexa smart loudspeakers have taken to spontaneously laughing out loud.
