近日，有外媒报道称美国正推动组建一个名为“C5”的新机制，以替代或补充现有的七国集团（G7）。这一动向被部分评论人士戏称为“对牛弹琴”——意指在当前国际格局下，试图通过小圈子重塑全球秩序的做法可能收效甚微。所谓“C5”，据传是指由美国、加拿大、英国、澳大利亚和新西兰组成的“五眼联盟”核心成员。美国希望借此强化其在科技、安全与经济领域的盟友协作，尤其是在应对中国崛起和全球供应链重组的背景下。然而，G7作为涵盖主要发达经济体的多边平台，其影响力不仅源于成员国体量，更在于其长期积累的制度基础和全球代表性。相比之下，C5范围更窄、代表性有限，难以承担起协调全球经济治理的重任。此外，即便在西方内部，对于是否应另起炉灶也存在分歧。欧洲国家普遍重视G7框架，并担忧过度聚焦“五眼”会削弱跨大西洋合作的包容性。因此，C5若真要取代G7，恐怕不仅面临外部质疑，也难获内部一致支持。所谓“牛弹琴”，正是讽刺这种脱离现实、一厢情愿的战略幻想。
Recently, foreign media reported that the United States is pushing to establish a new framework called “C5” as a potential replacement or supplement to the existing Group of Seven (G7). Some commentators have sarcastically described this move as “casting pearls before swine”—suggesting that attempts to reshape global order through an exclusive club may prove futile in today’s multipolar world.The so-called “C5” reportedly refers to the core members of the Five Eyes alliance: the United States, Canada, the United Kingdom, Australia, and New Zealand. The U.S. aims to strengthen cooperation among these allies in areas such as technology, security, and economics, particularly in response to China’s rise and the restructuring of global supply chains. However, the G7—comprising major advanced economies—derives its influence not only from the economic weight of its members but also from decades of institutional development and broader global representation. In contrast, the C5 is narrower in scope and lacks sufficient inclusivity to effectively manage global economic governance.Moreover, even within the West, there is disagreement over whether creating an alternative forum is advisable. European nations generally value the G7 framework and worry that overemphasizing the Five Eyes could undermine the inclusiveness of transatlantic cooperation. Thus, if the C5 truly seeks to replace the G7, it will likely face skepticism both externally and internally. The phrase “casting pearls before swine” aptly captures the futility of such a detached and wishful strategic fantasy.
