“16＋1合作”于自2012年建立启动以来，经过5年多的不断发展日益成为中国与中东欧国家在各领域合作交流的重要平台。中东欧国家方面，目前，16个中东欧国家中已有11个成为了欧盟成员国，而其剩余的5个中东欧国家也把加入欧盟作为重要国策和未来发展方向。这使得中国与中东欧国家开展合作时必须考虑与欧盟的关系因素。事实上，“16＋1合作”与中欧合作密不可分，中国政府自发起“16＋1合作”框架之始就强调该合作平台是中欧关系、中欧合作的重要内容和有益补充。正如2016年中国—中东欧国家领导人里加峰会上，中国总理李克强所指出的：“16＋1合作”是中欧合作的组成部分和有益补充，有利于推进中欧四大伙伴关系和五大平台建设，有利于欧洲平衡发展，有利于欧洲一体化。

　　The 6th Prime Minister Summit of China-CEEC was held in Budapest， Hungary on November 27， 2017， which marks the fifth year of China-CEEC cooperation.
