Former Secretary of State of the United States Madeleine Albright said world's countries, including the U.S., need to unite not divide in fighting against the COVID-19 pandemic.

"You can't solve these problems alone. It doesn't take a genius to figure out that climate change affects everybody, or nuclear proliferation, or pandemics, and that therefore diplomacy is the language where we try to develop partnerships and work together, "the former senior diplomat said in an interview with ABC Australia on Friday.

She pointed out that the politicization of the pandemic is a disturbing problem as she noticed.

"What I've been troubled by is the politicization of it, and not taking responsibility and blame placing," the senior diplomat said.

"We unfortunately did not make decisions early enough, according to what I've read," she expressed her concerns as commenting on how Australia and the U.S. handled the public health crisis.

Albright, the first female U.S. secretary of state, served the administration under Bill Clinton from 1997 to 2001.

The senior diplomat, who also worked as the U.S. ambassador to the United Nations for four years before her state department role, said that China is also a part of the cooperation.

"We are blaming the Chinese for what happened. But the bottom line is we depend on the masks that they make. If they are the ones that invent the vaccines, will we say no?" she said. 

Her words came as the U.S. administration, under the leadership of President Donald Trump, has been firing blame-shifting rhetoric at China amid mounting criticism of the administration's responses.

Australian politician, Peter Dutton, was also accused by Beijing in parroting the U.S.'s acts.

The Chinese ambassador to the U.S. Cui Tiankai has warned against "anything-but-China" or the "ABC" mindset during a Bloomberg New Economy webcast that discusses U.S.-China relations.

"Some politicians are so preoccupied in their efforts for stigmatization, for groundless accusations," Cui said, urging the public to pay more attention to the views of scientists instead of politicians.
