The White House said that Biden raised to Abiy recent airstrikes that continue to cause civilian casualties and suffering in Africa's second most populous nation.
The statement added that the leaders ``discussed ways to accelerate dialogue toward a negotiated ceasefire, the urgency of improving humanitarian access across Ethiopia, and the need to address the human rights concerns of all affected Ethiopians, including concerns about detentions of Ethiopians under the state of emergency.''
Abiy on Twitter described the conversation with Biden as ``candid'' and both agreed ``there is great value in strengthening our cooperation through constructive engagement founded on mutual respect.''
The leaders' call comes days after Ethiopia's government announced an amnesty for some of the country's most high-profile political detainees, including opposition figure Jawar Mohammed and senior Tigray party officials.
The more than yearlong war has created a devastating humanitarian crisis. The conflict entered a new phase in late December when when Tigray forces retreated into their region amid a Tigray military offensive and Ethiopian forces said they would not advance further there.
Biden announced in November he was moving to cut Ethiopia from a US trade program over its failure to end the conflict in the Tigray region that has led to ``gross violations'' of human rights.
