Recent data point to a weakening euro zone economy, the European Central Bank's Olli Rehn told, adding that interest rates would remain at the current level until monetary policy goals have been met.

"Yes, the most recent data point to a weakening of the economy," Rehn, the Finnish central bank chief, told Handelsblatt business daily.

He attributed it to greater uncertainties outside the eurozone, such as the trade conflict between the United States and China but also pointed to uncertainty over Brexit, protests in France, fiscal issues in Italy and slower industrial production in Germany.

Asked whether the ECB would meet its inflation target of just under 2 percent, he said wage increases in recent months had not had much impact on core inflation.

He also said ECB policymakers would in their coming meetings address the question of Targeted Long-Term Refinancing Operations (TLTRO).
