While China and the US have clashed in recent weeks over the coronavirus pandemic, a phone call between the leaders of the two countries suggests tensions could be easing.

Chinese state media is reporting that President Xi Jingping told President Donald Trump he hoped the "US will take substantive actions to improve Sino-US relations."

He also called for the two countries to work together to tackle the virus and said Beijing "wishes to continue sharing all information and experience with the US", according to state broadcaster CCTV.

President Trump sounded a positive tone, tweeting that he had a "very good conversation" with President Xi, and that both leaders discussed the pandemic "in great detail".

"China has been through much & has developed a strong understanding of the virus. We are working closely together. Much respect," he wrote.

The US President and his Secretary of State Mike Pompeo angered Beijing this month by repeatedly referring to "the Chinese virus" when discussing the COVID-19 outbreak first detected in the Chinese city of Wuhan.

President Trump has since dropped the term amid accusations of racism, in another small sign of easing tensions between the two world powers.

Just finished a very good conversation with President Xi of China. Discussed in great detail the CoronaVirus that is ravaging large parts of our Planet. China has been through much & has developed a strong understanding of the Virus. We are working closely together. Much respect! — Donald J. Trump (@realDonaldTrump) March 27, 2020

Earlier this month a foreign ministry spokesman in Beijing also suggested in a tweet that the US military brought the virus to Wuhan.

This prompted President Trump to accuse China of spreading misinformation, and the US president repeatedly attacked China's lack of transparency and the slowness of its initial response to the outbreak.

President Xi said Sino-US relations were at a "critical juncture", CCTV reported, adding that cooperation was mutually beneficial and "the only right choice."

Friday's call also took place as the US overtook China as the country with the most confirmed coronavirus cases, the pathogen has now infected more than 82,400 people in the world's largest economy.

During the call, President Xi said China had shared information about the epidemic with the World Health Organization and other countries including the US in a "timely" manner throughout.

"Infectious diseases are the common enemy of mankind, and do not recognise borders or races," he said.

Some provinces, cities and companies in China have provided medical supplies and support to the US as well, President Xi added.

At an emergency videoconference chaired by Saudi Arabia Thursday, which both leaders joined, G20 nations pledged a "united front" in the fight against the coronavirus.

The group said they would inject $5 trillion into the global economy to counter the pandemic amid forecasts of a deep recession.
