China announced Wednesday a nationwide loosening of Covid restrictions following protests against the hardline strategy that grew into calls for greater political freedoms.

Under the new guidelines, some asymptomatic and mild cases of Covid-19 can now quarantine at home, ending a requirement that all positive cases be isolated in centralized government facilities.

The frequency and scope of PCR testing will also be reduced, the National Health Commission said.

Mandatory mass testing — long a tedious mainstay of life in zero-Covid China — will be restricted to "high-risk" areas and schools.

People travelling between provinces will also no longer require a negative test taken within 48 hours, and they will not be have to test upon arrival, according to the new rules.

The announcement came in the wake of rare demonstrations across the country against the ruling Communist Party's hardline zero-Covid strategy.

The protests expanded into calls for more political freedoms, with some even calling for President Xi Jinping to resign.

Wednesday's announcement came hours after the government released further data showing the crippling economic impacts of zero-Covid.

Imports and exports plunged in November to levels not seen since early 2020.

Imports in November fell 10.6 percent year-on-year, the biggest drop since May 2020, according to the General Administration of Customs. Exports fell 8.7 percent over the same period.
