Samoa's deputy prime minister, Misa Telefoni Retzlaff, says his government needs guarantees if a loining plant is to go ahead on Savai'i.
Misa says he's just completed another round of discussions with the StarKist cannery company's executives in Apia.
StarKist is cutting back its large cannery operation in neighbouring American Samoa, saying that costs there are making the plant uneconomic.
Misa says Samoa is prepared to invest in upgrading the power supply on Savaii if StarKist commits to a loining plant.
"We really want them to say yes and the other thing we have to be very careful about, we can not spend one cent on infrastructure unless we have a total binding legal agreement with them on the fact the loining will happen."
