The World Bank Group leverages resources and expertise from a number of internal and external partners. Internally, World Bank-administered global programs and partnerships provide significant resources for knowledge generation and brokering in a range of areas of expertise, including transparency, extractive industries and the energy sector, public-private partnerships and water and sanitation. Externally, the World Bank Group is partnering with a range of actors, including other multilateral development banks and bilateral donors. For example, the World Bank and the Asian Development Bank engaged the G20 leadership on ways to unlock the potential of green urban transport at the summit in Los Cabos, Mexico. The World Bank has also taken a lead role in influencing and setting the infrastructure agenda in several international fora, including G20 Leaders' Summits and the Rio+20.
