歐中內衣大戰緣起於2005年中旬，而真正結束於2007年十月，肇因世貿組織架構下的紡織與服裝條約終止。即使最終雙方得以簽訂條約限制中國成衣進口數量，但事件的發生，著實造成歐盟內部成員國分裂，一派支持設限；另一派則持自由貿易口號。歐中紡織紛爭中，鑑於義大利擁有最大的紡織工業，爲了國家利益，義大利是強烈要求對中成衣設限的會員國。貿易紛爭的發生最大原因歸咎於義大利藉宣稱捍衛歐洲紡織市場與代表歐盟紡織業者的利益，進行內部廣泛的動員與跨國結盟，迫使主張自由貿易派失利以及歐中紡織糾紛的加劇。爲求清楚觀察義大利內部動員情形，透過採用普南雙賽局分析所衍生的三層賽局（歐盟與中國、歐盟內部與義大利內部等三個層次），以完整剖析歐盟內部及歐盟與中國間的互動。本文藉由歐中紡織紛爭的案例分析來證明內部因素影響國際談判。
”Bras war” took place in 2005 and is terminated really in October 2007 because of phase-out of ATC (Agreement of Textile and Clothing). Although both sides reached the agreement on the reduction of volumes of Chinese clothes this event had divided EU Member States into two parts (in favor or against quotas towards China). During the Sino-EU textile dispute Italy was one of most influential countries being eager to impose the safeguards on China in the wake of national interest in textile and clothing sector. As a result, the Sino-EU trade row occurred because of the strong Italian mobilization to rally other Member States to stand on its side and on behave of the European textile producers to defend the EU interest. To observe Italian fierce reaction it is better to adopt three-level games, which is derived by Putnam's two-level games, can bring us a clear-cut picture in which Italy tended to transfer its national interest to international negotiation table. This paper, through an examination of Sino-EU trade disputes, offers an explanation about how the domestic politics influence the outcome of international negotiation. With this case study domestic factor shows its influence on international politics. We conclude that domestic politics can't ignore as international negotiation proceeds.
