The two Oslo agreements themselves don't contain this sort of earmarking. There was a sort of informal understanding that Oslo would be a stepping stone toward a real Palestinian state, and that hasn't happened, but it would be hard to put most of the blame on Israel. Arafat walked away from a very serious statehood offer in 2000, for example.
From your comments it sounds like you might have been misled by some questionable sources, which would be understandable considering even top UN officials have spread rather blatant disinformation about Israel [1]. E.g. you also mention a famine against civilians, when we're actually about three orders of magnitude short of the number of starvations required to declare a famine.
