Trump said China may have started the coronavirus deliberately, as top advisers claim attacking Beijing may be the best way to for the president to save his job

• President Donald Trump has claimed that China may have allowed the coronavirus to spread deliberately.
• "But if they were knowingly responsible, yeah, then there should be consequences," Trump said of China's response to the disease.
• Trump's approach to China has veered between blaming it for the coronavirus outbreak and seeking to strike a more conciliatory tone.
• Top Republicans though, believe that Trump's best path to victory in November's presidential election is to take a tough line against China and cast Beijing as "the bogeyman."

President Donald Trump warned of "consequences" for Beijing if China were found to have deliberately allowed the novel coronavirus to spread.

"It could have been stopped in China before it started and it wasn't, and the whole world is suffering because of it," Trump said at the daily White House coronavirus task force briefing on Saturday.

"If they were knowingly responsible, certainly," he said. "If it was a mistake, a mistake is a mistake. But if they were knowingly responsible, yeah, then there should be consequences."

The president did not specify what the consequences may be.

At the briefing, Dr Deborah Birx, the White House coronavirus task force coordinator, also cast doubt on revised Chinese figures, which raised the number of people killed by the outbreak in its epicenter in the city of Wuhan by 50%.

Birx said that China has a "moral obligation" to provide credible information to the rest of the world.

Trump's remarks come as he faces increasing pressure over his faltering handling of the outbreak, which has killed nearly 40,000 people in the US so far and where the number of infections is higher than anywhere else in the world.

The crisis has placed a spotlight on Trump's relationship with China, where the virus originated last year. In what critics say was an attempt to divert blame from his administration, Trump last week cut funding to the World Health Organization, which he accused of being too "China-centric."

In recent weeks he has both sought to play up China's role in the crisis, referring to the coronavirus as the "China virus" in press briefings. By contrast, he has also attempted to strike a conciliatory tone, praising Chinese President Xi Jinping's handling of the crisis after a March 27 call with the leader. After the call, he also dropped the "China virus" tag.

Trump is reportedly wary of antagonizing China's leader, with the US dependent on Chinese medical supplies as it battles the disease, and does not want to destabilize further markets rocked by unprecedented US unemployment figures not seen since the Great Depression.

But top advisers are privately urging Trump to double down with his attacks on China. The New York Times reported on Saturday, claiming that if he can successfully pin the blame on the government in Beijing, it may be his best hope of reversing a slide in the polls and saving his job.

"Trump has always been successful when he's had a bogeyman and China is the perfect bogeyman," Chris LaCivita, a longtime Republican strategist, told the publication.
