Patrick Galenon, who is also one of the main trade unionists, wrote to French Foreign Minister Sébastien Lecornu as France scheduled a high-level roundtable in Paris next month on the legacy of nuclear weapons testing in the South Pacific.
Mr Galenon said that since 1995, the CPS has provided $ 800 million to treat a total of 10,000 people with one of 23 cancers recognized by law as the result of radiation.
He said France had to reimburse these expenses if it wanted to restore confidence.
A 2010 French law recognized for the first time that nuclear tests were not clean, but the compensation for beneficiaries is only made on the basis of national solidarity, not because the French State recognizes a responsibility.
Mr Galenon said France’s responsibility must be anchored in law because the rest is sentimentality and politics.
He said France would also have to shoulder the payment for ongoing oncology services, which cost the CPS more than $ 50 million per year.
Between 1966 and 1996, France carried out 193 nuclear weapons tests in French Polynesia.
The Moruroa and Fangataufa test sites remain excised from French Polynesia and are French no-go zones.
