Europe exchange traded funds are outperforming U.S. equities as the Eurozone’s economic recovery continues to gain momentum. However, investors should still be aware of some potential hurdles.

“The recovery has now taken hold,” Siim Kallas, an Estonian politician, vice president of the European Commission, said in a New York Times article.

The European commission believes that the Eurozone will gain momentum this year and continue through 2015.

“Deficits have declined, investment is rebounding and, importantly, the employment situation has started improving,” Kallas said.

Nevertheless, Kallas pointed to potential threats ahead, including tensions with Russia, extended period of low inflation and the need for continued reforms.

The commission projects that the Eurozone could expand 1.6% this year and touch 2% next year, compared to a 0.1% increase last year. Across the EU, unemployment rate will continue to dip to 10.5% this year and to 10.1% next year, compared to a jobless rate of 10.8% in 2013.

Moreover, the commission warned that France and Italy could lag behind the rest of the Eurozone. Observers fear that France could slip back into stagnation while Italy’s government tries to enact reforms and loosen its debt targets. The commission estimates that the French economy will grow 1% this year and 1.5% next year while Italy’s economy will expand 0.6% this year and 1.2% next year.
