Local health experts said that test kits would greatly help Vietnam deal with the situation.

Since late January 2020, health agencies of the two countries have shared information and data to combat Covid-19.

Hanoi and Ho Chi Minh City top the country's localities for the number of coronavirus cases and have several virus hot spots.

A longer stay-at-home period is believed to enable Hanoi to better identify infected cases and contain the virus.

Vietnam's test kits have been certified by the World Health Organization and the UK to be sold in Europe.
