MADRID (Reuters) - The different inflation levels in euro zone countries make the European Central Bank's monetary policy action challenging, Spanish Economy Minister Nadia Calvino said on Friday.
"We see a (inflation) downward trend in our country which contrasts with the upward trend in a large part of the European Union," she told reporters.
"There are different macroeconomic and inflation situations in the different countries and that is a challenge for the ECB when articulating a unique monetary policy."
