印度跳反后,中国反其道而行!给莫迪甜头,力挺印美关税战打到底
Sou Hu Cai Jing· 2025-08-24 05:49
在王毅外长访问印度的那几天,中印关系的暖意逐渐显现,双方展示出了相互合作的意愿。印度总理莫迪坦言,中印应当成为合作伙伴,而印方官员苏杰生 则明确表示对"一个中国"政策的认同。同时,中方也做出了松口的姿态,同意恢复对印度化肥、稀土和盾构机的出口,这些都是印度当下亟需的资源和技 术。然而,谁又能预想到,就在几天之后,印度的态度大变,一方面否认了对台的表态,另一方面还进行了号称能覆盖中国的核导弹试射。 这一反复无常的举动让人难以捉摸,面对如此"跳反"的行为,中国不但没有表现出愤怒,反而在公开场合上支持印度与美国进行贸易战,承诺的物资还陆续 向印度发货。这种软硬兼施的态度,令外界对印度的算盘和中国的策略充满了疑问。 要想理清这一复杂局面,必须先了解印度为何在最初愿意向中国示好。简单来说,印度确实迫切需要中方提供的几种重要资源。首先,印度农业在很大程度 上依赖化肥,特别是在中方暂停供应后,印度农民苦不堪言;其次,稀土问题同样不容轻视,印度85%的稀土磁铁依赖于中国进口;此外,盾构机在印度的 基础设施建设项目中更是不可或缺的。因此,王毅访问印度时中方的松口,实际上给了印度一枚"定心丸",这也促使莫迪愿意发表一些亲善言辞, ...
