China reported a drop in new coronavirus infections for a fourth day as drastic curbs on international travellers reined in the number of imported cases, while policymakers turned their efforts to healing the world's second-largest economy.
The city of Wuhan, at the centre of the outbreak, reported no new cases for a sixth day, as businesses reopened and residents set about reclaiming a more normal life after a lockdown for almost two months.
