Ramaswami: Even a pharmaceutical group, Shengjingtong, was one of the thousands of companies that transitioned to become part of China's mask-making army. Aided by generous government subsidies, within 11 days, they were making more than 10,000 N95 masks a day. By mid-March, China was making 200 million face masks a day — more than 20 times the amount it made at the start of February. Of this, 6,00,000 are N95 standard masks, used by medical personnel and healthcare workers.
