US officials believe China covered up the extent of the COVID-19 outbreak — and how contagious the disease is — to stock up on medical supplies needed to respond to it, intelligence documents show. Chinese leaders "intentionally concealed the severity" of the pandemic from the world in early January, according to a four-page Department of Homeland Security DHS intelligence report dated May 1 and obtained by the AP.

Marked "for official use only," the DHS analysis states that, while downplaying the severity of the virus, China increased imports and decreased exports of medical supplies. It attempted to cover up doing so by "denying there were export restrictions and obfuscating and delaying provision of its trade data," the analysis states.
