During the period, the region absorbed more than US$1.5 billion, or 10.6% of the total FDI capital flow into the country.
The figure only stood at 5-6% five years ago, Lam added.
In nine months, Can Tho city alone attracted US$72 million in five new FDI projects, along with an additional US$40 million in two existing projects.
As of early October, the Mekong Delta is home to 1,495 valid FDI projects worth a total of US$20.95 billion.
Lam said that most FDI firms, particularly those from Japan, often pay heed to device manufacturing and technology in the region.
Meanwhile, investment in the agro-fishery sector, which is viewed as one of the strengths of Mekong Delta localities, remains modest.
He noted that the fourth Vietnam-Japan Cultural and Trade Exchange in Can Tho city, which is slated for early November, will offer favourable conditions to introduce the potential of the city’s and other Mekong provinces’ agro-fishery sectors to Japanese investors.
