China further tightened its anti-pandemic measures in Beijing and across the country on Friday as scattered outbreaks continued ahead of the opening of the Winter Olympics in a little over two weeks.
The actions appear to reflect nervousness about a possible surge in cases ahead of the Beijing Games.
Beijing has ordered children at international schools to be tested starting next week and is barring air passengers who transited via a third point. Citizens are being told only to travel if absolutely necessary, with no guarantee they will be permitted to return if found to have visited a city or region where an outbreak occurred.
