Three large international vessels were registered at Yangpu Port on Thursday, the day Hainan launched island-wide special customs operations, a move that local officials say underscores the policy's role in accelerating the growth of the shipping sector.

Cai Yinghong, head of the Hainan International Ship Registration Administration, noted that the registrations reflect the momentum brought by the new customs regime.

"Their arrival demonstrates Yangpu's growing appeal as a shipping hub," he said, adding that the vessels are engaged in key areas, including cargo transport, engineering, and construction.
