WASHINGTON (AFP) - US Secretary of State Mike Pompeo and a top Chinese official on Wednesday (April 15) called for mutual coronavirus cooperation, signalling a bid to keep a lid on their countries' renewing tensions.

President Donald Trump's administration has berated China for not sharing data more quickly and said Tuesday it was freezing funds to the World Health Organisation for not challenging Beijing.

Pompeo renewed his push for "full transparency" in a call on Wednesday with senior Chinese official Yang Jiechi, but the State Department's tone was unusually positive.

Pompeo "noted the aid the American people delivered to the people of China in January - and continue to offer - and the high importance we attach to China's facilitation of medical supply exports to meet critical demand in the United States," the State Department said.

"The two sides confirmed their commitment to defeat the Covid-19 outbreak and restore global health and prosperity," it said.

In a summary of the conversation, Chinese official news agency Xinhua said Yang had indicated that "China stands ready to continue sharing information and experience on epidemic prevention and control with the United States."

The country would also work to implement the consensus reached among Group of 20 (G-20) nations - the world's largest economies - to keep global supply chains stable and promote economic stability, Xinhua said.

China is a vital source of masks and other supplies desperately needed by the United States, which has the highest number both of infections and deaths from the virus.

Trump and Chinese President Xi Jinping had appeared to reach a truce in a phone call late last month, with Trump and Pompeo afterward ending the provocative use of the terms "Chinese virus" and "Wuhan virus."

According to Yang, the two sides have since "maintained close communication on anti-epidemic efforts in line with the important consensus reached by the two heads of state," Xinhua said.

Yang also emphasised that it was "crucial" for the two countries to properly handle their relations and maintain healthy bilateral ties, Xinhua said.

Even if the rhetoric is more civil, Defence Secretary Mark Esper said on Wednesday that China should provide more information on the virus that originated in its metropolis of Wuhan.

"Even today, we see them withholding information. And so I think we need to do more and continue to press them to share," Esper told Fox News.

Trump's Democratic rivals say the WHO announcement was a dangerous attempt to divert attention from problems in the US response as Trump gears up for elections.

Trump himself had in January said he had the virus "totally under control" and praised China as transparent.
