强调本国利益优先，阻碍全球事务合作，美国“大退群”：将退出66个国际组织

Core Viewpoint - The article discusses the U.S. government's decision to withdraw from 66 international organizations, including the United Nations Framework Convention on Climate Change (UNFCCC), which is seen as a significant retreat from global cooperation and multilateralism [1][5][7]. Group 1: Withdrawal from International Organizations - The U.S. will exit 31 UN agencies and 35 non-UN organizations, including the UN International Law Commission and the UN Human Settlements Programme, as part of a broader review of U.S. participation in international organizations [2][4]. - The White House claims these organizations promote agendas contrary to U.S. interests, labeling them as redundant and inefficient [4][7]. Group 2: Impact on Climate Agreements - The withdrawal from the UNFCCC is particularly notable, as it is considered the cornerstone of major international climate agreements, including the Paris Agreement [5][6]. - Experts warn that this decision could hinder global efforts to reduce greenhouse gas emissions and may provide other countries with excuses to delay their climate commitments [6][8]. Group 3: Shift in U.S. Foreign Policy - The decision reflects a long-standing skepticism towards multilateral institutions, with the current administration prioritizing unilateral actions over international consensus [7][8]. - The U.S. government aims to concentrate taxpayer funds on enhancing its influence in specific UN standard-setting bodies, particularly in areas where it competes with China [8].
