地处北美西北角的美国阿拉斯加州，与俄罗斯的远东疆域之间仅隔一个白令海峡。 1853年，俄罗斯与奥斯曼爆发了这两大帝国自16世纪以来的第十次绞杀，因为这场战争中最长和最重要的战役在克里米亚半岛进行，史称"克里米亚战 争"。当时，英法两国权衡利弊后，决定站队已经式微的奥斯曼，以抵挡沙俄在欧陆继续做大。 与眼下的俄乌冲突一样，当年的那次兵戎相见，一打就是三年，耗尽了沙皇的国库，并以俄方失败告终；而英国则趁势加强了在北美的扩张，特别是英属 哥伦比亚（今加拿大西部大省），直接威胁到人烟稀少、易攻难守的俄属阿拉斯加。 为了争取美国牵制英国，沙皇亚历山大二世出于地缘政治考虑，于1867年以700万美元外加20万美元手续费（相当于每英亩2美分）的价格将阿拉斯加"贱 卖"给美国。 美国用于支付阿拉斯加的720万美元支票 158年后的今天，热衷做交易的特朗普作为当年"买方"美国的代表，在此设宴款待一直希望恢复昔日"卖方"俄罗斯荣耀的普京总统，商讨如何结束一场因 俄罗斯2014年收复克里米亚而引发的俄乌冲突。 这是一次多么具有反讽和象征意味的历史循环？ 对普京而言，阿拉斯加是一块刻在俄罗斯历史记忆中的旧疤，当年失去这块地藏丰富的土 ...

Core Viewpoint - The recent trade tensions between China and India, marked by India's imposition of tariffs on steel imports and China's anti-dumping investigation into medical equipment components, reflect deeper strategic rivalries rather than isolated economic disputes [1][3][10]. Trade Policies - India has imposed a 12% temporary tariff on imported steel products to protect its domestic industry from what it perceives as cheap Chinese imports, claiming it aims to curb the impact on local manufacturers [3][5]. - The Indian government has previously enacted selective bans on Chinese products, such as drone components and apps, while allowing American companies to operate freely, indicating a strategic alignment with U.S. interests [3][5]. Strategic Implications - The timing of India's tariff announcement coincided with the U.S. extending tariffs on Chinese goods, suggesting a coordinated effort to counter China [3][10]. - India's approach to balancing relations with major powers, including the U.S. and Russia, while simultaneously engaging in confrontational policies towards China, highlights its complex geopolitical strategy [5][10]. Economic Impact - China's response to India's tariffs includes a swift anti-dumping investigation into critical components for medical imaging equipment, which could significantly impact India's healthcare sector, as 65% of its high-end medical imaging devices are imported, with 40% from China [7][11]. - The potential expansion of China's countermeasures to include India's pharmaceutical and IT sectors, where India exports over $3 billion in drug raw materials to China, could lead to severe economic repercussions for India [7][11].
