US envoy on Horn peace mission
The conflict combines modern technology with World War I tactics
US special envoy Anthony Lake is holding talks in Ethiopia and Eritrea in a new attempt to broker an end to their 14-month border war.
He then left for Eritrea where he is expected to meet President Isaias Afwerki.
A special envoy from Algeria, which currently chairs the OAU, is also trying to bridge the differences between the two countries.
Earlier this year, both Ethiopia and Eritrea accepted the OAU plan in principle but have not been able to agree on the practicalities of its implementation.
On Wednesday, Ethiopia issued a statement saying it would continue fighting because Eritrea was not serious about peace.
The statement came at the same time the UN Security Council expressed optimism about peace efforts and urged both governments to accept the plan.
The two Horn of Africa neighbours went to war on 6 May 1998, each accusing the other of invading.
Since then, Ethiopia has demanded a withdrawal from land it says Eritrea has invaded.
Eritrea argues that it has not invaded Ethiopian territory, but merely reclaimed land which was rightfully its own in terms of colonial border treaties.
Tens of thousands of soldiers and hundreds of civilians have died, and nearly half a million residents on both sides of the border have been driven from their homes.
The framework agreement requires both sides to agree a ceasefire and begin redeploying troops immediately after the fighting stops.
Both would have to sign a formal ceasefire agreement first.
Both would also have to accept OAU military observers, working with the UN, to supervise troop redeployment.
The ceasefire agreement was revised during the recent OAU summit in Algiers, where both sides came under diplomatic pressure to resolve their differences.
But both governments, while announcing their acceptance of the plan, have blamed the other for setting new pre-conditions and changing interpretations.
