United States Agency for International Development (USAID) Administrator Samantha Power Sunday hailed Sudan's transition during a visit to Khartoum where she discussed with officials the country's humanitarian needs.
Sudan has been going through a transition since the ouster in April 2019 of president Omar al-Bashir.
USAID said ahead of her visit that Western nations sought to support the civilian-backed transitional government after decades of authoritarian rule.
"My emphasis in this trip … is squarely on Sudan's economic development needs and the ongoing humanitarian needs," she told a news conference in Khartoum.
Power said the United States aimed to help Sudan "reinvigorate the economy" and "to attract foreign investment".
She later met the foreign minister, and will also meet other top officials before leaving on August 3.
On Saturday, Power visited Sudan's western Darfur region where she talked to people displaced during the grisly conflict there. She also met North Darfur Governor Nimir Mohammed Abdel Rahman and discussed how the United States can partner with Sudan to help implement the Juba Peace Agreement, particularly the security measures necessary for the people of Darfur to live safely.
Fighting broke out in 2003 when rebels, complaining of systematic marginalization, took up arms against the Bashir regime.
The UN says the years-long conflict killed 300,000 people and displaced 2.5 million.
In December, Washington removed Sudan from its list of state sponsors of terrorism, and later also vowed to clear the country's arrears with the World Bank.
From Khartoum, Power will head to Addis Ababa for talks with Ethiopian officials on humanitarian access to the conflict-ridden Tigray region.
