India and China, two of the top greenhouse gas emitting countries, signed an agreement Wednesday to cooperate on climate change policy. The two nations will share ideas about how to domestically reduce greenhouse gas emissions and how to deal with international climate change negotiations so that the interests of developing nations are protected. This show of solidarity comes before the international climate change conference in Copenhagen this December. A recent UN report suggested that India, China, and other developing nations will need extensive foreign aid from developed nations to help their economies grow in a sustainable manner.
