Hanoi places nine affected areas in lockdown after it confirmed 21 cases within a week.

Hanoi said it will focus on improving the grassroots healthcare system and imposing home treatment of asymptomatic and mild symptoms cases.

Hanoi Party Secretary Dinh Tien Dung said the year 2022 continues to be chosen as the "Year of discipline, responsibility, action, creativity, and development."

Along with drastic measures to help business recovery, Hanoi would soon reopen attraction spots, cultural and spiritual heritage.

The event is expected to raise the businesses' concerns and recommendations and improve the business environment.
