Ethiopian Prime Minister Abiy Ahmed has begun a visit to Eritrea, days after the two countries agreed to end a two decade-old border dispute.
He was welcomed in the Eritrean capital Asmara by President Isaias Afewerki. The trip follows a visit to Addis Ababa by an Eritrean delegation.
Mr Abiy, who took office in April, has accepted a ruling awarding disputed territory to Eritrea.
Eritrea won independence from Ethiopia in 1993 after a lengthy conflict.
But within five years the neighbours were fighting over remote border areas, including the town of Badme.
The land was awarded to Eritrea by a 2002 border commission ruling, but Ethiopia refused to accept it and retained its troops there.
The two sides have remained on a war footing since then.
