Translation of "border line" into Chinese

This is the sum of cross-border line sections which, if constructed, would provide intercountry rail connectivity.

这是跨界线路路段的总和,一旦修建完工,将提供国家间铁路的互联互通。

Accordingly, those other benchmarks may have to be pursued on the basis of the current border line.

因此,也许不得不在目前边界线的基础上执行其他标准。
