A French Polynesian opposition politician is warning that his side might sue France if it fails to remove radioactive substances from its former weapons test site at Moruroa.
Moetai Brotherson, who is a member of both the French National Assembly and the French Polynesian assembly, has warned of the risk of the atoll collapsing because of damage caused by the atomic blasts.
Mr Brotherson said he was still awaiting an answer from a range of French ministers.
"Either they won't respond which basically would be a 'no' or they will answer 'no' for specific reasons, and I would suspect the main reason for saying 'no' would be 'we don't have the technology, we don't have the finances'.
"If they answer 'no' we're going to act on that answer and maybe sue the French government."
Last month, Mr Brotherson told the UN decolonisation committee that over the past 10 years France had spent more than $US100 million just to monitor the cracks on Moruroa.
Moruroa has remained a no-go zone despite the end of testing 23 years ago.
