Ethiopia’s prime minister said his landlocked nation of 100 million people will begin using the port of neighboring Eritrea, its longtime sworn enemy, after a day of historic talks with President Isaias Afkwerki.

“Ethiopia will resume using Eriteria’s port,” Abiy said in remarks broadcast by both nations’ state broadcasters while the prime minister was attending a state dinner hosted by Isaias.

According to this report,the leaders of Ethiopia and Eritrea signed a “joint declaration of peace and friendship” on Monday.

“The Agreement, which specifies five pillars, was signed this morning at State House by President Isaias Afwerki and Prime Minister Abiy Ahmed,” Eritrea’s information minister, Yemane Gebremeskel wrote on Twitter alongside a photo of the two men seated at a table in front of their nations’ flags.
