The Vanuatu opposition MP Willie Jimmy says the Capital Investment Immigration Plan has not raised the revenue that Treasury expected and should be scrapped.
The government this week reaffirmed provisional support for the CIIP scheme which aims to raise government revenue through citizenship sales linked with investment in Vanuatu.
The Prime Minister Joe Natuman says support for the plan is subject to a review of the CIIP and negotiations between a government taskforce and the Hong Kong-based agent for the scheme.
Mr Jimmy says he has been opposed to the programme and the constitutional amendment to allow dual citizenship since it was proposed last year.
"There is not yet even a single vatu that came in from that programme. Andf there's hardly any investment at all going on today in Vanuatu under the CIIP programme: nothing, zero. I can confirm that."
