According to top climate ambassador of France, she is concerned regarding the slow speed of progress on a negotiating text, which will be significant for a new international agreement on global warming in Paris. However, Laurence Tubiana also added that negotiators from approximately 200 countries were working on development of the document and it was clarified that the French government would be acting in response to see if more development is there.

These comments came after climate ministers met to take international climate talks further prior to UN summit in Paris later this year.

Earlier, the UN secretary general Ban Ki-moon said that the negotiations were continuing at "a snail's pace" following discussions in Bonn reduce the 90-page text by only four pages. A new streamlined version was published last Friday and the two officials were controlling it and said that the "pace was slow". They said that an urgent requirement was there to speed up the work as a result of serious time constraints.

The document, which governments are looking forward to consider in Paris, should be much shorter, with points of disagreement resolved and removal of swathes of potential text at present in brackets.

Tubiana said hours prior to the latest version, "We are all very concerned, but it's progressing. What we do as a normal presidency [of the talks] anxious to have a result in Paris not at the last minute, is to say we need something to be cleared in October".
