在这方面，问题在于缺少承诺，欧盟宁可选择权宜的非正式安排带来的便利，而不愿对联合国、国际货币基金组织和世界银行等对有效的多边主义至关重要的机构进行改革。
In this case, the problem comes down to a lack of commitment, with the EU choosing the convenience of informal and ad hoc groupings over the challenge of reforming key institutions like the United Nations, the International Monetary Fund, and the World Bank, which are essential for effective multilateralism.
