BEIJING (Reuters) - Siemens (DE:SIEGn) has no interest in becoming a white knight for German robot maker Kuka (DE:KU2G), which is the target of a 4.5 billion euro (3.57 billion pounds) takeover bid by Chinese home appliance maker Midea <000333.SZ>, Siemens' chief executive said.
"If we had been interested, we would have acted on it some time ago," Joe Kaeser told German broadcaster ntv in an interview on Sunday.
Midea's bid has fanned a furious debate over Chinese takeovers in Europe, with politicians such as German Economy Minister Sigmar Gabriel calling for tougher restrictions. It has also prompted Berlin to consider whether Kuka's technology is crucial for the digitalisation of German industry, an economic priority.
Kaeser, speaking to the broadcaster on the sidelines of Chancellor Angela Merkel's trade visit to Beijing, said he believed Gabriel, who is also Vice Chancellor, was relaxed about Kuka's situation.
"I don't believe that Mr Gabriel has a concern," Kaeser said.
"As Economy Minister, he's looking out for his country... in that sense, it's quite natural that he should look at alternatives," Kaeser added.
Gabriel said earlier this month there was an effort under way to develop an alternative offer for Kuka.
Germany's Sueddeutsche Zeitung daily reported that Gabriel had spoken to German car manufacturers and Siemens about mounting a possible counter-bid for Kuka. But sources close to the government and Siemens told Reuters the idea had met with little enthusiasm.
Norbert Roettgen, who heads the German parliament's foreign affairs committee, said legal and economic action was needed to prevent the loss of key technologies and know-how.
"Germany and Europe are faced with the question of whether there are ... certain business areas that should be protected for strategic reasons and to ensure national and European security," he told the Ruhr Nachrichten newspaper on Monday.
"Robot maker Kuka may well be such a case."
Andy Gu, vice chief executive of Midea, told Germany's Handelsblatt newspaper on Sunday that his company's bid for Kuka was motivated by business interests and aimed at helping the German company target the huge Chinese market. It was a not a political undertaking, he said.
"We are a private company. It's not important to us what the Chinese government demands," the newspaper quoted Gu as saying.
Gu said Kuka would remain independent, adding that he expected Chinese authorities to approve the takeover, according to the newspaper.
