Yemen is a low income country that is highly dependent on declining oil resources for revenue. Petroleum accounts for roughly 25% of GDP and 70% of government revenue. Yemen has tried to counter the effects of its declining oil resources by diversifying its economy through an economic reform program initiated in 2006 that is designed to bolster non-oil sectors of the economy and foreign investment. In October 2009, Yemen exported its first liquefied natural gas as part of this diversification effort. In January 2010, the international community established the Friends of Yemen group that aims to support Yemen's efforts towards economic and political reform, and in August 2010 the IMF approved a three-year $370 million program to further this effort. Despite these ambitious endeavors, Yemen continues to face difficult long term challenges, including declining water resources and a high population growth rate.
