China has classified coronavirus epicentre Wuhan as a low-risk area, days after it revised the city's death toll by 50 per cent, even as 16 new COVID-19 cases were reported in the country, health officials said on Sunday.

President Donald Trump has cast doubt on the accuracy of China's official coronavirus death toll, terming it "unrealistic" and claiming that the actual number was "way ahead" of the US' which is not the world's "number one" country in terms of COVID-19 fatalities.

The number of the coronavirus cases in the US crossed 700,000 on Friday, while over 35,000 people have died from the disease, as President Donald Trump assured his people that America was "very close" to seeing the light "shinning brightly" at the end of the tunnel.

China's coronavirus death toll mounted to 4,632 on Friday after it revised the fatality figures by 50 per cent in Wuhan, the epicentre of the outbreak, as Beijing faced mounting international criticism of under-reporting of the COVID-19 data.

A record number of 4,591 Americans have died in the last 24 hours due to the deadly novel coronavirus in the US, which has the highest number of COVID-19 casualties in the world.

The US has provided nearly USD 5.9 million in health assistance to India to contain the spread of COVID-19, the State Department has said.

Washington: The confirmed coronavirus death toll in the United States surpassed 30,000 on Thursday, according to a tally by Johns Hopkins University.

China on Thursday dispatched 650,000 coronavirus medical kits to India to help fight the COVID-19 pandemic, Indian Ambassador to Beijing Vikram Misri said.
