You are right about the long-standing dispute and arguments from both sides. I was referring to 1974 since that was the last time two countries agreed on document where borders were mentioned although in a very general way. That constitution was also foundation for succession rights and deeds of federal republics after declaring independence.

I mentioned 90s since that was the fist time international commission was involved in trying to help in determining the borders. But it was all in vain since one side states that border is determined by data based on cadastre and one is claiming that the river is the border. The riverbed changed during the years and that created fertile ground for political manipulations.
