One way to do this was to build up huge stockpiles of foreign currency reserves.

实现这一想法的方法之一是建立巨额外汇储备。

In 2011 the country became a net importer of energy for the first time since 1984, further eroding its foreign currency reserves, now at their lowest in six years.

2011年该国自1984年之后再次成为能源净进口国家，这进一步吞噬了其外汇储备，达到了六年来的最低值。

The energy minister said the companies would be chosen on the basis of their ability to operate without seeking any foreign exchange in their central bank, which is nearly run out of foreign currency reserves.

该国能源部长表示，将根据公司在不向央行寻求任何外汇的情况下的运营能力来选择这些公司，其央行的外汇储备已几乎耗尽。
