A lobby group in Vanuatu says there are many unanswered questions surrounding the new fish processing plant at Black Sands near the capital, Port Vila.
This comes as China has given the Vanuatu government the keys to the new plant.
But the lobby group, the residents against processing tuna, says the government has said very little about the plant.
It says a review of an environmental impact report on the plant found there were some outstanding issues that needed to be addressed.
But the chairman of the group, Michael Taurakoto, says the government has not made the report public.
He also adds that the government has been telling people that there is nothing to worry about.
"We just want information, if it's really true that there is nothing to worry about then I think people given proper answers for the outstanding issues that have been identified in the report."
Michael Taurakoto says there are also environmental concerns over Port Vila harbour with an expected increase in fishing boats delivering their catch.
