HANOI -- After shutting down four industrial parks in northern Vietnam on Tuesday, authorities are scrambling to smother outbreaks of COVID-19 at other parks to protect the country's position as a regional manufacturing hub.
Authorities in Ho Chi Minh City, the country's southern commercial center, say they are taking new measures to accelerate mass testing to detect infections among workers. The city has 17 export processing zones, industrial parks and high-tech zones where 1,500 companies employ some 280,000 workers and around 2,600 experts.
