"You shouldn’t rush when there is still smoke coming from a house that was burning. It is simply not safe to do so."
"As long as the eurozone has problems with some of its own members, don’t expect us to be enthusiastic about joining."
Belka said the Eurozone suffers from a "little bit of a vicious circle," due to the divergence among member economies.
Though it would not be problem to build some kind of fiscal union among the northern economies of the Eurozone, he warned that "as long as we have problems in some countries, it's more difficult to build up a solid foundation for the real fiscal union in the eurozone."
When asked about the Greek debt crisis, Belka said the situation contributed to his lack of confidence in the single currency. The National Bank governor called the deal which was recently reached between Greece and its creditors a "temporary respite but not a solution," and said that what he preferred to call a "debt re-profiling" would be necessary for Greece sooner or later.
