French President Emmanuel Macron has told the Paris Peace Forum that multilateralism is under threat. We examine the issue in this programme. This year's Forum is focusing on efforts to beat the Covid-19 crisis and $425 million has been pledged, $100 million of them from France alone. International cooperation is vital to making progress not just on the Covid-19 question, but also on matters of security, defence, business, climate change and coming back to the Forum's chief aim: peace.
