US President Donald Trump on Tuesday said of late he has not spoken with his Chinese counterpart Xi Jinping and has no plans to do so.

"No, I have not spoken to him, one. No, I do not. I have no plan to speak to them," Trump told reporters at a White House press conference. He expressed anger over China's inability to prevent the spread of the coronavirus out of the country, from where it originated.

"Make no mistake, we hold China fully responsible for concealing the virus and unleashing it upon the world. Could have stopped it, they should have stopped," Trump said as he also lashed out at the World Health Organization (WHO) for siding with China on this issue. "They were really a puppet of China," he said.

Trump also slammed former vice president Joe Biden, who is his Democratic challenger in the November presidential polls, for being "soft" on China. "By contrast, my administration acted very early to ban travel from China, from Europe, saving all of these lives. Incredible. And I want everyone to know, I want every citizen to know that we are using the full power of the federal government to fight that China virus and keep our people safe. Through Operation Warp Speed, we will deliver a vaccine in record-breaking time," he said.

"He (Biden) said the idea that China is our competition is really bizarre. He is really bizarre. He said China is not a problem. No. Nobody has ripped us off more than China over the last 25, 30 years, nobody close, and he says China is not a problem. Now he takes it all back. Now he wants to be mister tough guy. But for years, 47 years, he never came out against China, never said anything bad, just the opposite," the president said.
