缺乏统一性是中国谈判单一条约的主要动机之一：中国想要确保中资企业在所有欧盟成员国获得平等市场准入权，避免因需要遵守不同制度而产生的成本和复杂性。
This lack of uniformity is a major motivation for China to negotiate a single treaty: it wants to ensure that its enterprises have equal market access in all EU member countries and avoid the costs and complications associated with adhering to different regimes.
