State-owned Vietnam National Shipping Lines on Wednesday started building a new wharf at Cam Ranh Seaport in the central province of Khanh Hoa.
The work is part of a plan to upgrade the port to receive bigger ships.
The three-phase VND520-billion project will enable the seaport to accommodate ships of up to 50,000 deadweight tons, the government said in a report.
Cam Ranh Port is a major port in the Central Highlands and South Central region and the cargo volume it handles increases 10 percent every year on average, putting pressure on existing facilities, the government said.
The new wharf will also raise the total cargo volume at the port to 2.5-3 million tons a year, compared with only 1.3 million tons in 2009.
Deputy Prime Minister Hoang Trung Hai said the project will help ease congestion at seaports in Ho Chi Minh City. He said the authorities in Khanh Hoa Province have to ensure needed resources are invested in the key project.
