This situation is due to sanctions barring US companies from doing business with Sudan, introduced in November 1997 by then president, Bill Clinton. The sanctions prohibited the trade in most goods and services between the US and Sudan, and blocked Sudanese government property in the US. With over 40 million people and an abundance of natural resources, the country presents numerous investment opportunities. But despite its opportunities, Sudan remains a tough place to do business. However, landlocked South Sudan continues to export its oil through a 1,610‑km pipeline that runs across Sudan to the Red Sea.
