Raila Odinga promised on Friday to unite the country after elections a year ago in which around 100 people were killed mainly in clashes between opposition supporters and security forces.
The shocking statement is possibly to decrease the political pressure in the richest economy in East Africa as well as the center of regional security, diplomacy and trade.
Both Kenyatta and Odinga had said in a joint statement that they agreed to establish a new office staffed by advisers.
The meeting did not happen as the result of pressure from Western countries, there was no external pressure on the two leaders from western countries, specifically the U.S. for the leaders to hold the talks ahead of USA secretary of state Rex W. Tillerson's three-day visit beginning on Friday.
"Time has come for us to confront our differences because they are becoming too entrenched", said Odinga.
The truce comes months after Kenyans went to two violent elections in the last quarter of 2017.
President Kenyatta was sworn in for a second term last November.
About 150 people were killed in the aftermath of the election, which Mr Kenyatta won after an opposition boycott.
He said the security situation is still dependent on AMISOM and Somalia partners, and that the planned UN/AU withdrawal of AMISOM by 2020 needs to be carefully reviewed.
"I can state that the meeting was between two people and does not bear the imprint of NASA summit as it ought to be".
"This is the moment for our country to stand together and build the bridges of friendship, brotherhood and unity so as to take this country to another level", said Mr Ruto.
"We refuse to be the leaders under whose watch Kenyans lead into a failed nation".
In other words, the "reconciliation" between Uhuru Kenyatta and Raila is a fundamental betrayal of the hundreds of innocent Kenyans who have lost their lives fighting for democracy and in defence of Raila Odinga's stolen electoral victories of 2007, 2013 and 2017. "They have successfully engineered this", said Aly Khan Satchu, an independent analyst in Nairobi.
Moses Kuria, a legislator for Kenyatta's Jubilee party said the meeting could be the start of ending the cycle of disputed elections and their ruinous impact on economic growth.
"It's a really good step towards harmonizing the country", said Brian Wanjoki, a pedestrian.
