阅读材料，回答下列问题。

材料一  在新中国成立前夕，***就提出，“我们在国际上是属于以苏联为首的反帝国主义战线一方面的。真正的友谊的援助只能向这一方面去找，而不能向帝国主义战线一方面去找。”在帝国主义和社会主义两大阵营中间，“中立”是不可能的，中国必须站在以苏联为首的和平民主阵营一边。明确宣布“一边倒”，打破了帝国主义的幻想。这一外交方针对新中国建设起了重大作用。

——靳德行《中华人民共和国史》

材料二  “一边倒”外交政策的实施不仅使新中国在经济援助、外交等方面倚重苏联，并且政治体制、经济体制的某些方面也照搬前苏联经验，产生了许多弊端，走了许多弯路。同时也加剧了中美关系的冻结程度，限制了中国外交向纵深的发展。

——游艳丽《美国对华政策与新中国“一边倒”外交政策之联系》
