In 1991 the Budapest agreement had Ukraine relinquish its nukes in exchange for security guarantees from both Russia and the US, amongst others.
Actually the Budapest Memorandum (from 1994, not 1991) explicitly avoided any mention of security guarantees as such, which has been seen as one of its major shortcomings.
It asked that the signatories respect each others' borders, which was in itself significant. But this by itself does not amount to any kind of security guarantee.
