The Fiji government's gift of 1.6 acres of state land in the capital to Indian Prime Minister Narendra Modi has come under scrutiny.
India's government plans to build its new high commission and residence at the Botanical Gardens in Suva.
Former civil servant Allen Lockington has started a petition to stop the project.
He said the Indian mission should be relocated as it will have an impact on visitors to the gardens and the environment.
"Trees will be cut down. Of course, construction will encroach into Botanical Gardens and we just hope that no trees will be cut down - exotic trees.
"Since it's going to be a high commission, there will be high security. Will freedom of movement be easy for the people who go to the gardens?"
The Suva City Council said public objections to the re-zoning of the piece of land at the Gardens will close on 25 February.
