German corporate takeovers by foreign entities have had a positive impact on the country in terms of investment, according to an executive at Kuka AG, the robotics company targeted by China's Midea Group Co.

"We've had a lot of US companies and Japanese companies doing it and now the Chinese guys are doing it," Stefan Lampa, head of Kuka's robotics unit, said at a trade fair in Munich. "I've never seen any negative effects from those kinds of things, it's always been positive effects."

Lampa's comments, which he said were about foreign investment in general, come following an offer from Midea to build a stake in Augsburg-based Kuka.
