The Samoan government has struck a deal with the Chinese company, Huanan Fisheries, to allow it to use the port at Apia for transhipment.
Huanan supplies to Asian markets and has been looking at consolidating itself in Samoa by pushing for a fish processing plant.
The Government has not confirmed any deal on the plant, but the company has been eyeing the Satitoa wharf at Aleipata, on the south coast of Upolu, as a possible location for a cannery.
The Prime Minister, Tuila'epa Sa'ilele Malielegaoi, said the company's multimillion dollar projects in other parts of the Pacific have given the government the confidence that the investment will be a success.
