China cleared all of its high-risk areas for COVID-19 on Sunday.
The last high-risk area, a community in the border city of Ruili in southwest China's Yunnan Province, was lowered to a medium-risk area for COVID-19 at noon on Sunday.
The latest epidemic resurgence in the city started in early July, with a total of 114 locally transmitted cases reported since then. To date, 93 of them have been cured and discharged from hospital, and 21 are still being treated, according to the city's headquarters for COVID-19 prevention and control.
The Chinese mainland on Sunday reported no new locally transmitted COVID-19 cases, the National Health Commission said in its daily report on Monday.

Four suspected cases arriving from outside the mainland were newly reported, of which three were reported in Shanghai and one in Beijing.
No new deaths were reported on Sunday, the commission added.
