In the statement by Dr Asad Khan Minister of Pakistan to the UN concernign Rio+20 he said:
"Clearly the challenge of sustainable development has become far too acute and big for any country to tackle. The UN undoubtedly, has a central role to play in this regard, particularly in advancing the global sustainable development to meet new and emerging challenges in an increasingly globalized world.
The need for an integrated and coordinated response to arrest, reduce and rverse the negative trends is, therefore, vital. In this regard we look forward to an early decision on convening a world summit on sustainable development in 2012 in Rio, Brazil to carry out a comprehensive review of the implementation of Sustainable Development Agenda since Stockholm and to delineate a roadmap for future actions to effectively deal with new and emerging sustainable development challenges."
