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.
Smartly turned out staff waited in masks and gloves to greet customers at entrances to the newly-reopened Wuhan International Plaza, home to boutiques of luxury brands, such as Cartier and Louis Vuitton.

Authorities in Ningbo said they would encourage national banks to offer preferential credit of up to 100 billion yuan to the eastern port city's larger export firms. The city government will subsidize such loans, it said in a notice.
