Airlines, both Chinese and non-Chinese, also face the risk of their flight routes being suspended temporarily if a certain number of infected passengers are detected on arrival in China. Reported daily cases in China are currently far lower than in other major countries but the Chinese government is acutely aware of potential wider transmissions due to its dense urban populations and highly developed transport network. Travellers to mainland China, regardless of nationality, face tough requirements prior to travel including multiple medical tests and stringent quarantine rules upon entry. China sharply reduced transport links with other countries as the coronavirus, which first emerged in the central Chinese city of Wuhan in late 2019, spread around the world last year. China reported 25 new confirmed COVID-19 cases in the mainland for June 21, of which 23 were imported infections, the National Health Commission said on Tuesday.
