European Union member states have reached a unanimous agreement to eliminate air and maritime internal border controls with Bulgaria and Romania.
欧盟成员国一致同意取消与保加利亚和罗马尼亚的空中和海上内部边境管制。

The Council of the EU says the move paves the way for the two countries to gain full access to the Schengen area.
欧盟理事会表示，此举为两国全面进入申根区铺平了道路。

Originating as an intergovernmental project among five EU member states in 1985, Europe's Schengen area of free movement has gradually expanded through seven enlargement stages.
欧洲申根自由流动区始于1985年，是欧盟五个成员国之间的一个政府间项目，经过七个扩大阶段逐步扩大。

With the inclusion of Romania and Bulgaria, the Schengen area is set to grow to 4.5 million square kilometers, accommodating a population of 450 million.
随着罗马尼亚和保加利亚的加入，申根区将增至450万平方公里，可容纳4.5亿人口。
