Mexico assures climate delegates: no secret talks

Mexico's foreign secretary is telling the global climate conference in Cancun there will be no secret negotiations in the meeting's final days, assuring delegates they will not see a repeat of the last hours of 2009's Copenhagen climate summit.

Foreign Secretary Patricia Espinosa says the Mexico hosts will work with full transparency in the coming days in the difficult, slow-moving annual talks to find ways to combat climate change.

In closed-door midnight talks at last December's summit in Copenhagen, Denmark, U.S. President Barack Obama and a handful of other leaders produced a "Copenhagen Accord," a document envisioning only voluntary reductions in global-warming gases. It disappointed treaty nations ranging from Europe to small island states facing seas rising from global warming, and outraged some with the closed nature of the decision-making.
