Donald Trump believes China's handling of the coronavirus pandemic is proof that Beijing "will do anything they can" to make him lose his re-election bid in November.
In an interview with Reuters in the Oval Office, the US President talked tough on China and said he was looking at different options in terms of consequences for Beijing over the virus. "I can do a lot," he said.
Mr Trump has been heaping blame on China for a global pandemic that has killed more than 60,000 people in the United States and thrown the country's economy into a deep recession, putting in jeopardy his hopes for another four-year term.
The Republican president, often accused of not acting early enough to prepare the United States for the spread of the virus, said he believed China should have been more active in letting the world know about coronavirus much sooner.
Asked whether he was considering the use of tariffs or even debt write-offs for China, Mr Trump would not offer specifics. "There are many things I can do," he said. "We're looking for what happened."
"China will do anything they can to have me lose this race," he said.
He believes Beijing wants his Democratic opponent, Joe Biden, to win the race to ease the pressure Mr Trump has placed on China over trade and other issues.
"They're constantly using public relations to try to make it like they're innocent parties," he said of Chinese officials.
He said the trade deal that he concluded with Chinese President Xi Jinping aimed at reducing chronic US trade deficits with China had been "upset very badly" by the economic fallout from the virus.
A senior Trump administration official, speaking on condition of anonymity, said on Wednesday that an informal “truce” in the war of words that Mr Trump and Mr Xi essentially agreed to in a phone call in late March now appeared to be over.
The two leaders had promised that their governments would do everything possible to co-operate to contain coronavirus.
In recent days, Washington and Beijing have traded increasingly bitter recriminations over the origin of the virus and the response to it.
However, Mr Trump and his top aides, while stepping up their anti-China rhetoric, have stopped short of directly criticising Mr Xi, who Mr Trump has repeatedly called his “friend”.
Mr Trump also said South Korea had agreed to pay the United States more money for a defence co-operation agreement, but would not be drawn out on how much.
"We can make a deal. They want to make a deal," Mr Trump said. "They’ve agreed to pay a lot of money. They’re paying a lot more money than they did when I got here [in January 2017]."
The United States stations about 28,500 troops in South Korea, a legacy of the 1950-53 Korean War that ended in an armistice, rather than a peace treaty.
Mr Trump is leading a triage effort to try to keep the US economy afloat through stimulus payments to individuals and companies while nudging state governors to carefully reopen their states as new infections decline.
Mr Trump sounded wistful about the strong economy that he had enjoyed compared with now, when millions of people have lost their jobs and GDP is faltering.
"We were rocking before this happened. We had the greatest economy in history," he said.
He said he is happy with the way many governors are operating under the strain of the virus but said some need to improve. He would not name names.
Mr Trump's handling of the virus has come under scrutiny. Forty-three per cent of Americans approved of Mr Trump’s handling of the pandemic, according to the Reuters/Ipsos poll from April 27-28.
But there was some good coronavirus news, as Gilead Sciences said its experimental antiviral drug remdesivir was showing progress in treating virus victims.
Mr Trump is also seeking an accelerated timetable on development of a vaccine.
"I think things are moving along very nicely," he said.
At the end of the half-hour interview, Mr Trump offered lighthearted remarks about a newly released Navy video purportedly showing an unidentified flying object.
"I just wonder if it's real," he said. "That's a hell of a video."
