中美会晤落地后，特朗普宣布全球进入G2时代，俄欧日得坐另外一桌

Group 1 - The core idea presented is the emergence of a "G2 era," dominated by the economic powers of China and the United States, sidelining other nations like Russia, Europe, and Japan [1][13] - The combined GDP of China and the U.S. accounted for nearly half of the global total last year, highlighting their role as the dual engines of the global economy [2][12] - Economic actions or changes between China and the U.S. significantly impact the global economy, as seen during the trade war, leading to worldwide economic fluctuations [4][6] Group 2 - The sustainability of the G2 status is likely for the next few decades unless significant economic issues arise in either country, with China potentially surpassing the U.S. as the largest economy [6][12] - Political and diplomatic autonomy is crucial for maintaining the G2 position, which is a comparative weakness for Russia, Europe, and Japan [6][7][9] - Russia's economy is heavily reliant on energy exports, making it vulnerable to sanctions and conflicts, as evidenced by the impact of the Ukraine crisis [6][11] Group 3 - Europe and Japan lack political independence, often acting under U.S. influence, which limits their ability to emerge as global powers [7][9] - The G2 structure has gradually formed since the end of the Soviet Union, with the U.S. becoming the sole superpower, while other nations have struggled to achieve a multipolar world [11][13] - The acknowledgment of China's rise by U.S. figures like Trump reflects a significant shift in global power dynamics, moving away from U.S. dominance alone [13]
