Tuna exports in the first six months were worth US$553 million, a 56 percent rise year-on-year, according to data from the Vietnam Association of Seafood Exporters and Producers.
Exports to the U.S. all but doubled thanks to higher demand, especially for canned tuna.
Exports to members of the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) also rose sharply, especially to Canada (up 68 percent), Japan (up 26 percent) and Mexico (up 30 percent).
The EU market grew the slowest at 7 percent.
The association expected high growth for tuna export in the second half of the year, with export rising 45 percent from 2021 to $1.1 billion.
It warned rising fuel prices, which have kept fishing boats on shore, would affect supply.
