English to German Bus/Financial Economics EU economy

With France and Germany leading the way, the economy in the 12 ***nations that use the Euro currency*** grew at its fastest quarterly rate since 2000, a development that is expected to fortify the resolve of the European Central Bank to raise interest rates again this year.

Ist damit nicht die “Eurozone” gemeint, und reicht es evtl. auch aus, von “Euro-Nationen” (mittlerweile 13?) zu sprechen?

DiV für eure Hinweise.
