Background | In 1902, ABD AL-AZIZ bin Abd al-Rahman Al Saud captured Riyadh and set out on a 30-year campaign to unify the Arabian Peninsula. In the 1930s, the discovery of oil transformed the country. Following Iraq's invasion of Kuwait in 1990, Saudi Arabia accepted the Kuwaiti royal family and 400,000 refugees while allowing Western and Arab troops to deploy on its soil for the liberation of Kuwait the following year. A burgeoning population, aquifer depletion, and an economy largely dependent on petroleum output and prices are all major governmental concerns. | Chad, part of France's African holdings until 1960, endured three decades of civil warfare as well as invasions by Libya before a semblance of peace was finally restored in 1990. The government eventually suppressed or came to terms with most political-military groups, settled a territorial dispute with Libya on terms favorable to Chad, drafted a democratic constitution, and held multiparty presidential elections in 1996 and 1997. In 1998, a new rebellion broke out in northern Chad, which sporadically flares up despite two peace agreements signed in 2002 and 2003 between the government and the rebels. Despite movement toward democratic reform, power remains in the hands of an ethnic minority. |

Economy - overview | This is an oil-based economy with strong government controls over major economic activities. Saudi Arabia has the largest reserves of petroleum in the world (26% of the proved reserves), ranks as the largest exporter of petroleum, and plays a leading role in OPEC. The petroleum sector accounts for roughly 75% of budget revenues, 45% of GDP, and 90% of export earnings. About 25% of GDP comes from the private sector. Roughly 4 million foreign workers play an important role in the Saudi economy, for example, in the oil and service sectors. The government in 1999 announced plans to begin privatizing the electricity companies, which follows the ongoing privatization of the telecommunications company. The government is supporting private sector growth to lessen the kingdom's dependence on oil and increase employment opportunities for the swelling Saudi population. Priorities for government spending in the short term include additional funds for the water and sewage systems and for education. Water shortages and rapid population growth constrain the government's efforts to increase self-sufficiency in agricultural products. | Chad's primarily agricultural economy will continue to be boosted by major oilfield and pipeline projects that began in 2000. Over 80% of Chad's population relies on subsistence farming and livestock raising for its livelihood. Cotton, cattle, and gum arabic provide the bulk of Chad's export earnings; Chad began to export oil in 2004. Chad's economy has long been handicapped by its landlocked position, high energy costs, and a history of instability. Chad relies on foreign assistance and foreign capital for most public and private sector investment projects. A consortium led by two US companies has been investing $3.7 billion to develop oil reserves estimated at 1 billion barrels in southern Chad. Oil production came on stream in late 2003. |
