Zoellick's statement said the money, which will come from the International Development Association, the World Bank's arm for low-income countries, was for "immediate recovery needs and longer-term reconstruction."
"We need to respond strongly to the crisis at hand, but we need to do it without losing sight of important economic reforms," he said. "This disaster underscores Pakistan’s fiscal vulnerability and dependence on foreign aid."
Zoellick and Shaikh discussed plans for institutional and governance reforms in Pakistan in the wake of a disaster which has crippled the south Asian nation's economy, the statement said.
The World Bank pledged to help Pakistan set up systems for tracking aid flows, and monitoring and evaluating the whole process to tackle waste and corruption.
