BERLIN, May 18 (Reuters) - The Kuwait Investment Authority (KIA) has warned Germany it may cut back its commitment to ploughing funds into Europe's largest economy if the Berlin government regulates sovereign wealth funds.

Many German politicians are nervous about the influence sovereign wealth funds can wield and their capacity to buy leading national companies or key national infrastructure.

KIA managing director Bader al-Saad told weekly magazine Der Spiegel that Germany's reservations about wealth funds had not yet influenced the investment activities of the KIA, which manages the Gulf Arab state's oil-generated assets.

"But we are very concerned," he added.

"We still consider Germany an economic anchor in Europe, even in the world. We still like to invest in Germany. But in the future, any regulations on sovereign wealth funds in Germany could limit our engagement in your country."

German Finance Minister Peer Steinbrueck is due to travel next week to the Arabian Gulf region, where he is expected to meet managers at sovereign wealth funds to improve their relations.

The German government plans to extend existing legislation that gives Berlin a veto on takeovers of defence firms to include other industries, though Steinbrueck has said Germany does not want to scare off sovereign wealth funds.

"We are very surprised by the Germans' fear of sovereign wealth funds. We have been in Germany for more than 45 years," Saad said.
