The success of stabilization and currency liberalization in 2003 has led to significant increases in exports and imports in recent years, although imports have increased much less rapidly: while exports had more than doubled to US$15.5 by 2011, imports had risen to US$6.5 billion only, reflecting the impact of the government's import substitution policies designed to maintain hard currency reserves.
2003年的穩定和貨幣自由化政策成功，出口量和進口量近年來大幅增加，即使進口量增速較慢，出口量在2011年增加超過1倍至155億，而進口量只增加至65億美元，反映政府進口替代政策以維持外匯儲備的影響。
