The northeast Chinese city of Jilin is imposing fresh restrictions on travel in order to contain a new coronavirus outbreak, with six new cases reported on Tuesday.
Jilin has emerged as the source of a potential new wave of infections and the neighbouring city of Shulan was forced to adjust the risk level to "high" from "medium" at the weekend.
"The current COVID-19 situation is quite complex and severe, and there is huge risk that the virus will spread further," said Gai Dongping, Jilin's vice mayor.
