Germany's Environment Ministry and opposition Greens party have warned Siemens not to take part in a planned French nuclear deal with Libya, Handelsblatt reported. French President Nicolas Sarkozy signed a memorandum of understanding for a nuclear energy deal with Libya during a visit there last week.
France's Areva has been tipped to supply a nuclear reactor to Libya to supply drinking water from sea water and some Germans are worried that Siemens will get involved due to its 34 percent stake in a nuclear power joint venture with Areva.
"We must know what Siemens says about this unethical business," Michael Mueller, a Social Democrat parliamentary state secretary at the Environment Ministry told Monday's edition of Handelsblatt.
The paper also quoted Greens politician Margareta Wolf as warning Siemens not to go ahead.
"For the good of its image and to show it is a responsible company, Siemens would do well not to play with fire and get involved with this," Wolf told Handelsblatt, noting that getting export approval would be difficult.
Siemens does not comment on issues relating to Areva NP.
Sarkozy's offer of nuclear cooperation with Libya has angered a number of German lawmakers who see it as part of a growing trend of the Frenchman's "go-it-alone" approach to foreign policy.
