BEIJING -- China Monday expressed strong opposition to embroiling China in US electoral politics, in response to a memo exposed by news outlet Politico that urged US Republican candidates to address the COVID-19 crisis by aggressively attacking China.

The 57-page strategy document, obtained by Politico last Friday, is focused on three main lines of assault: That China caused the virus "by covering it up," that Democrats are "soft on China," and that Republicans will "push for sanctions on China for its role in spreading this pandemic," Politico summarized.

"Why have some political forces in the United States spared no effort in smearing and attacking China in the name of the pandemic? The answer is self-evident," said Foreign Ministry Spokesperson Geng Shuang at a press briefing.

"If the news report is true, we cannot help but ask who is spreading disinformation," Geng said.

The Chinese side firmly objects to some US politicians utilizing China for canvass purpose and jeopardizing China's interests in the name of the pandemic, Geng stressed.
