Yes, it is in access agreements. But the adopting of Euro is'nt sure. Firstly ... there is no time limit :wink: and secondly ... why to respect a treaty infracted by counterparties :evil: (see the euro-zone Pact of Stability). Now, a referendum on Euro is discussed in Hungary and Czech Republic drifts to something similar. My opinion: It is stupid to unify stable and saturated economies with dynamic economies in transition into one monetary zone. We need different interest rates, floating exchange rate helps to cope with economic fluctuation etc. Maybe in 30 years it will be more profitable.
