Vietnam's pangasius sector is suffering from restrictions imposed by the Vietnamese government to control the COVID-19 pandemic, making it difficult for the inexpensive whitefish to reach global markets, one market expert said.

Vietnam has been among the hardest-hit Southeast Asian nations, and the government has imposed strict measures to limit the spread of the virus.

Traveling between provinces in Vietnam has been restricted since the end of May, and since July 9 factories have been required to keep workers inside the premises at all times if they want to continue operating, according to Jean-Charles Diener, owner and director of inspection and consultancy firm OFCO Group.
