Weijia Jiang was left shocked by the president's response in her second spat with him in a month.
Donald Trump told a Chinese-American reporter to "ask China" after she questioned him about why he was making the COVID-19 crisis into a competition.
Weijia Jiang, who has previously clashed with the president, was left astounded by Donald Trump's answer as he then refused to allow another female reporter to ask a question because she gave Ms Jiang time to respond.
During Tuesday's daily White House coronavirus press briefing, the CBS reporter asked: "You've said many times that the US is doing far better than any other country when it comes to testing.
"Why does that matter? Why is this a global competition to you when every day Americans are losing their lives and we're still seeing more cases, every day?"
Mr Trump responded: "They're losing their lives everywhere in the world and maybe that's a question you should ask China - don't ask me, ask China that question.
Mr Trump responded: "They're losing their lives everywhere in the world and maybe that's a question you should ask China - don't ask me, ask China that question.
"When you ask them that question you may get a very unusual answer."
The reporter looked shocked by his answer as the president pointed to CNN's Kaitlan Collins, who asked her colleague if she wanted a follow-up question.
