Today, Kerry said the West is "not giving up" on the peninsula, "but we did not come (to Geneva) to talk about Crimea."
Each side came to the Geneva talks armed with a very specific set of demands, and the West and Kiev had aimed to persuade Moscow to demobilise the militias.
Ukraine's Security Service said it was detaining 10 "Russian spies" arrested over the past six weeks on suspected missions to stir up unrest in the country, further implying Russia's role in the destabilisation of the country.
Russia however has blamed Kiev's interim leaders -- installed by Ukraine's parliament in February after the overthrow of Yanukovych following months of protests -- for pushing the country dangerously close to civil war.
The agreement also called on all sides to refrain from violence, intimidation and provocation, as well as to reject extremism in all shapes.
Kerry told reporters that notices were sent to Jews in a Ukrainian city believed to be in the east, asking them to identify themselves as Jews -- a move he condemned as "grotesque".
"In the year 2014, after all of the miles travelled and all of the journey of history, this is not just intolerable, it's grotesque."
