BEIJING (AP) — Another 259 COVID-19 cases have been reported in the southern Chinese island province of Hainan, where some 80,000 tourists have been stranded by pandemic restrictions. Authorities declared Hainan’s beach resort city Sanya a COVID-19 hot spot Saturday and imposed a lockdown, confining Chinese citizens and expatriates to their hotels on what they had hoped would be a holiday from tight restrictions around much of China. Tourists wanting to depart Sanya have to test negative for the coronavirus on five PCR tests over seven days.
