The IBRD focuses on middle income and creditworthy poor countries, while IDA focuses on the poorest countries in the world. 国际复兴开发银行侧重帮助中等收入国家和信誉良好的贫困国家，而国际开发协会则侧重帮助世界上最贫困的国家。
Used, for example, in reference to allocation of IBRD funds to IDA where the funds made available by the Bank are used before other funds. 例如，国际复兴开发银行向国际开发协会转拨资金时，采用的原则是首先使用世界银行的资金，然后才使用其他来源的资金。
