The United States stepped up its pressure on China over the coronavirus pandemic, with President Donald Trump saying his administration was trying to determine where the deadly disease originated from.
Secretary of State Mike Pompeo also called on Beijing “to come clean” on what it knows.
At a White House news conference on Wednesday, Trump was asked about reports of the virus escaping from a laboratory in Wuhan, where the coronavirus first appeared.

“We are doing a very thorough examination of this horrible situation that happened,” he said.
Asked if he had raised the subject in his conversations with Chinese President Xi Jinping, Trump said: “I don’t want to discuss what I talked to him about the laboratory, I just don’t want to discuss, it’s inappropriate right now.”
At least 136,000 people around the world have now died from the disease, with almost 31,000 in the US alone. More than two million people have been diagnosed with the virus, while at least half a million have recovered.

Trump’s top diplomat, Pompeo, meanwhile told Fox News Channel after Trump’s news conference, “we know this virus originated in Wuhan, China,” and noted that the Institute of Virology was only a handful of miles from the market, where people first came down with the disease.
“We really need the Chinese government to open up” and help explain “exactly how this virus spread,” Pompeo added.
“The Chinese government needs to come clean,” he said.
The state-backed Wuhan Institute of Virology dismissed reports that the virus may have been artificially synthesised at one of its laboratories or escaped from its facility as far back as February.
Deadly consequences for delay
Trump and Pompeo’s comments follow an Associated Press news agency report, which blamed Chinese authorities for failing to immediately disclose information about the human-to-human transmission of the virus, also known as COVID-19, which allowed the virus to spread beyond Wuhan.
Fox News claimed on Wednesday that the virus originated in a Wuhan laboratory as part of China’s effort to demonstrate that its efforts to identify and combat viruses are equal to or greater than the capabilities of the United States.
This report and others have suggested the Wuhan lab where virology experiments took place and lax safety standards there led to someone getting infected and appearing at a nearby “wet” market, where the virus began to spread.

Trump and other American officials have also been expressing deep scepticism about China’s officially declared death toll from the virus of around 3,000 people, when at least 30,000 people have already died in the US.
On Wednesday, the US president returned to the subject, saying the United States has more cases “because we do more reporting”.
“Do you really believe those numbers in this vast country called China, and that they have a certain number of cases and a certain number of deaths; does anybody really believe that?” he said.
Scientists are still trying to determine the source of the virus, although the broad scientific consensus remains that COVID-19 originated in bats and spread to humans via an intermediary host.
On Tuesday, General Mark Milley, chairman of the Joint Chiefs of Staff, said that US intelligence indicated that the coronavirus probably occurred naturally, as opposed to being created in a laboratory in China, but that there was no certainty either way.
Trump’s critics, meanwhile, see his latest statements as an attempt to “shift the blame”, as the outbreak in the US continues to grow.
A report published over the weekend blamed Trump’s halting action and infighting in his administration for causing the delay in the US response, resulting in more deaths.
