Beijing has tightened entry restrictions after new reports of local infections of COVID-19 in various regions across China, local authorities said on Sunday.

Inbound travelers from areas with locally-transmitted cases must provide negative nucleic acid results within two days and undergo a 14-day health observation after arriving in Beijing, said Pan Xuhong, deputy head and spokesperson of the municipal public security bureau.
