The dispute adds to mounting opposition to Phoenix Life Sciences International, which claims its drug can treat diabetes.
Phoenix Life has wasted no time since obtaining approval from Vanuatu's government to manufacture drugs last October.
In March, it broke ground on a clinic and pharmacy in Port Vila and recruited a former Health Ministry director general.
But its diabetes-treating drug has prompted scepticism from health experts and Vanuatu's doctors' association, who want an ethics committee formed.
