Most new cases and deaths have been reported in Hubei province, the epicenter of the epidemic.
In all, more than 68,500 people have been infected and at least 1,669 have died worldwide, officials say. The vast majority of cases, and almost all deaths, occurred in mainland China, with the largest concentration in Hubei.
The count in Hubei increased dramatically on Thursday after officials changed the diagnostic criteria for counting new cases. The government now considers cases diagnosed in clinical settings, including the use of CT scans, and not just those confirmed with specialized test kits.
In an interview with Reuters news agency on Friday, China's Foreign Minister Wang Yi said the outbreak was "above all, under control".
"We have taken the most correct, rigorous and decisive measures," he said, rejecting widespread criticism that the authorities suppressed warnings and restricted vital information in the early days of the outbreak.
The minister also told Reuters that some of the travel restrictions imposed on Chinese citizens by other countries were an overreaction and were likely to be eased.
"I'm sure these countries are reflecting on this as the situation evolves," he said, adding, "because at the end of the day, these countries need to interact with China."
Speaking at the Munich Security Council on Saturday, the director of the World Health Organization, Tedros Adhanom Ghebreyesus, called for vigilance around the coronavirus, but warned against sowing fear and hysteria through false information.
