The factory, to be converted from an industrial building by China Construction First Group, will be able to turn out 250,000 masks each day, it said, adding that work began on Monday and was set to be completed by Saturday.
The rapid pace and makeshift nature of the plant mirror measures taken in the virus epicenter of Wuhan, in the central province of Hubei, where buildings have been converted to treat infected patients, or hospitals built from scratch, in days.
Producers of masks and other protective equipment around the world have been unable to meet demand in the wake of the outbreak, which has killed more than 1,700 people in China.Last month, CMmask, a Chinese mask maker that supplies 30% of the domestic market, said daily orders for 5 million masks were more than 10 times its usual level.
