White House Press Secretary Jay Carney said the agreement "is consistent with what we have advocated in calling for a de-escalation of the violence, constitutional change, a coalition government, and early elections."
The White House called for "immediate implementation" of the agreement:
"... we call for immediate implementation of the initial steps -- an end to the violence, amnesty and security normalization, and passage of the constitutional package in the Rada -- to provide space for the negotiations to begin on formation of a technocratic coalition government."
One of those initial steps, parliamentary reinstatement of the 2004 Constitution, was accomplished Friday.
The agreement was facilitated by French Foreign Minister Laurent Fabius, Polish Foreign Minister Radoslaw Sikorski, and German Foreign Minister Frank-Walter Steinmeier, all of whom arrived in Kiev on Thursday to meet with Yanukovych. A Russian representative witnessed the signing of the agreement, the White House added.
