Latvia would, however, \"need to remain vigilant\" on inflation, the European Commission warned, calling on the Baltic country to maintain \"a prudent fiscal policy\" and keep \"domestic demand on a sustainable path.\" \"Latvia\'s desire to adopt the euro is a sign of confidence in our common currency and further evidence that those who predicted the disintegration of the euro area were wrong,\" EU Economy Commissioner Olli Rehn said.
