The French environment minister, Jean-Louis Borloo, has postponed a Pacific trip shortly after it was officially announced.
Officials say his agenda has become too busy with discussions about a carbon tax and two international conferences on environmental problems caused by global warming.
Mr Borloo was due to arrive in French Polynesia today for a two-day visit to see what efforts are being made in the territory in environmental research, conservation and education.
The minister was also due to make a one-day visit to the Tuvalu capital, Funafuti.
No date has been given when Mr Borloo will now make the visit.
