The Chinese city of Wuhan has no remaining cases in its hospitals, health officials said.
But the country remains on alert for a second possible wave, with Beijing reimposing some of its lockdown measures and other cities seeing new quarantines, the Daily Mail reported.
Wuhan and the province of Hubei were put in lockdown near the end of January, with roads sealed, trains and planes cancelled and residents unable to move freely for more than two months.
The city is still testing residents regularly despite relaxing most restrictions.
The city had reported 46,452 cases, 56 per cent of the national total. It saw 3,869 fatalities, or 84 per cent of China’s reported, yet disputed, total.
National Health Commission spokesman Mi Feng announced: ‘The number of new coronavirus patients in Wuhan was at zero, thanks to the joint efforts of Wuhan and medical staff from around the country.’
The focus has since shifted to the northeast border province of Heilongjiang, which has seen large numbers of imported coronavirus cases entering from Russia.
The border town of Suifenhe, with its 70,000 population, went into lockdown at the start of the month while nearby Harbin, home to 10 million, has become the new battlefront.
And 1,000 miles away in Beijing, the authorities opened gyms and swimming pools only to quickly close them again to prevent any spread.
The district of Chaoyang is home to many expats and international offices and was put down into quarantine measures after travellers began to return, infecting Beijing locals who had stayed at home.
There were no signs of any worry yesterday as people packed into a flower market in Suzhou city, in east China’s Jiangsu province.
