Chinese President Xi Jinping, in a call with his US counterpart Donald Trump, said that the two countries should "unite to fight" the coronavirus, state media reported.
The two countries have clashed in recent weeks over the virus, but Xi told President Donald Trump that China "wishes to continue sharing all information and experience with the US," said state broadcaster CCTV.
The two leaders appeared to strike a conciliatory tone after Trump 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.
Following the call from Xi, Trump said in a Twitter post that the two leaders were "working closely together".
Friday's call also took place as the US overtook China as the country with the most coronavirus cases -- the pathogen has now infected more than 82,400 people in the world's largest economy.
Xi said Sino-US relations were at a "critical juncture", CCTV said, adding that cooperation was mutually beneficial and "the only right choice."
"I hope that the US will take substantive actions to improve Sino-US relations, and both sides can work together to strengthen cooperation in fighting the epidemic," he said.
