Singh said the issues of food security, energy security and climate change were closely interlinked. "They have to be approached as a single undertaking if we are to give meaning to the concept of sustainable development."

Noting that climate change will be an important subject of discussion, the Prime Minister said, "It is the developing countries that are the worst affected by climate change. What we are witnessing today is the consequence of over two centuries of industrial activity and high consumption lifestyles in the developed world. They have to bear this historic responsibility," he said, adding that India will actively participate in the international negotiations on climate change within the framework of the United Nations Framework Convention on Climate Change and the Bali Action Plan.

During his visit, the Prime Minister will have bilateral meetings with the leaders of the U K, Italy, Germany, Japan and Angola.
