This is caused by the low CPI rise in the first quarter this year and the drop in commodity prices.
But November’s CPI rose by 2.1 percent year-on-year due to rising fuel and commodity prices globally as economies start to recover from Covid-19.
Both government officials and analysts have warned of inflation risks next year.
Governor of the State Bank of Vietnam Nguyen Thi Hong said recently Vietnam will be able to keep inflation under the 4 percent threshold this year, but that there would be "very high risks" next year.
This is because Vietnam has a high trade openness and could face big risks of inflation in imports, she added.
