Despite the negative impact of COVID-19 on most of Vietnam's seafood export markets in 2020, exports to Australia and Canada, members of the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), experienced growth. Exports to Australia rose by 9% and to Canada by 14%. This trend continued in the first two months of 2021, with a significant increase in exports to these countries. Australia became the 7th largest market for Vietnamese seafood in 2020, but rose to 5th place in the first two months of 2021, largely due to a 59% increase in shrimp exports. Canada, the 6th largest market in 2020, also showed steady growth in the first two months of 2021. The article highlights the positive impact of the CPTPP on seafood exports to its member countries, including tariff preferences that are fully utilized by importers, contributing to the expected growth in seafood exports to Australia, Canada, and Chile in the coming months and throughout 2021.
