"Since this lawmaker said he has evidence that China is trying to sabotage Western countries in their vaccine development, then please let him present the evidence. There's no need to be shy," Chinese Foreign Ministry spokeswoman Hua Chunying said at a regular press briefing in Beijing on Monday.
Hua’s made the remarks in response to the Republican senator’s comments during an interview on BBC TV on Sunday.
“We have got to get this vaccine done. Unfortunately we have evidence that … China is trying to sabotage us or slow it down,” Scott said.
“China does not want us ... to do it first, they have decided to be an adversary to Americans and I think to democracy around the world,” he added.
When asked about the evidence, Scott declined to give any details but said it had come through the intelligence community.
Hua further said the development of a COVID-19 vaccine is not a competition between China and the United States, expressing hope that Washington will mirror China's pledge and offer any vaccine it develops to the world for free.
The new coronavirus, which causes a respiratory disease known as COVID-19, emerged in the city of Wuhan in December last year, incrementally affecting the rest of the world.
Beijing and Washington have time and again clashed over the virus spread, further increasing tensions between the world's two largest economies.
