China has administered 164.47 million doses of COVID-19 vaccines as of Saturday, the National Health Commission said on Sunday.
This represents around 24.5 million doses in the past six days, as the country's vaccine rollout continues to accelerate.
Last week a Chinese official said the country is expected to produce around 3 billion doses of COVID-19 vaccines by the end of the year.
Chinese health authorities on Sunday reported 10 new confirmed cases of COVID-19 and 22 asymptomatic cases, bringing the country's total to 90,410, while the death toll remained unchanged at 4,636.
The National Health Commission, in a statement, said all the new cases were imported infections originating from overseas.
The number of new asymptomatic cases, which China does not classify as confirmed cases, rose to 22 from 11 cases a day earlier.
The total number of confirmed COVID-19 cases in Mainland China now stands at 90,410, while the death toll remained unchanged at 4,636.
Meanwhile, in India new COVID-19 cases surged to a record of 152,879 on Sunday as the country battled a second wave of infections by pushing for faster vaccinations, with some states considering tougher restrictions to slow the spread of the virus.
India leads the world in the daily average number of new infections reported, accounting for one in every six infections reported globally each day, according to a Reuters tally.
Daily cases have set record highs six times this week, according to data from the federal health ministry.
Deaths have also surged, with the federal health ministry reporting 839 fatalities on Sunday - the highest in over five months - as hospitals and crematoriums in some parts of the country grappled with the worsening situation.
India's tally of more than 13.35 million cases is the third-highest globally, behind only Brazil and the United States.
Prime Minister Narendra Modi launched a four-day "Vaccination Festival" on Sunday to push more eligible Indians to get a COVID-19 shot.
"During this time we have to move towards optimum utilization of the country's vaccination capacity," Modi said in an open letter.
