Coronavirus: China steps up border controls in race to contain fast-spreading Delta variant
- Strict entry-exit rules, and daily tests for border staff in the mix as country rushes to keep infections down, with 20 task force teams sent to key port cities
- But prevention and control are being made more challenging by various sources of imported cases

The reinforcement of border controls came after Chinese immigration authorities vowed to tighten restrictions on entry and exit permits and to impose a temporary freeze on issuing passports for “non-urgent or unnecessary travel”.
Despite mounting calls for China to open its borders, the country has been pressing ahead with a “zero tolerance” approach to contain the spread of Covid-19 – by implementing strict lockdowns and restrictions at home and imposing stringent entry rules at the borders.
Only 335,000 passports were issued across the country in the first half of this year for people who study and work overseas or travel for business, accounting for just 2 per cent of the total for the same period in 2019, according to the National Immigration Administration.
Limiting the issuance of passports is one of the restrictive measures China has undertaken to minimise the risk of coronavirus outbreaks. The aim is to control the number of imported cases while authorities try to boost vaccination rates at home to reach herd immunity.
