The city of Shanghai prepared Thursday to reopen its eastern half and shut its western half, while authorities elsewhere announced the lifting of a citywide lockdown in the province hit hardest by China’s ongoing omicron-driven coronavirus outbreak.

Residents of the city of Jilin will be able to move about freely starting Friday for the first time in more than three weeks, state broadcaster CCTV said, citing a notice issued by the city. They will be required to wear masks and when indoors, stay one meter (three feet) apart. Public gatherings in parks and squares are prohibited.

The spread of COVID-19 has been brought under control in Jilin city but not in the rest of Jilin province, officials said at a news conference, according to CCTV. Some progress has been made in Changchun, the provincial capital and an auto manufacturing hub that has been locked down since March 11.
