Manzhouli, the land port city in Inner Mongolia Autonomous Region, announced that it has suspended all flights and public transportations, after finding 60 positive samples in the city's mass nucleic acid testing.
Starting from Saturday, flights, trains, buses and taxis in or from Manzhouli have been cut out. All entry and exit points of the city have implemented 24-hour traffic control, inspecting and monitoring people and vehicles entering and leaving the city, said local government officials at a news conference on Tuesday.
Except from medical and delivery personnel, all residents are strictly prohibited from leaving the city to minimize the risk of the outbreak dispersion.
A total of 60 positive samples were found in the city's first round of massive city-wide nucleic acid testing program starting Saturday, officials said.
Two areas in the city have been listed as high- and mid-risk areas for COVID-19.
